Major spoilers for Harry Potter and the Half-Blood Prince, with references to later Harry Potter instalments, follow.
I’ve finished Harry Potter and the Half-Blood Prince, and I’m not ready to rank it. It’s still lingering in my head.
I fell in love with the original sense of magic: discovering Hogwarts, meeting its ghosts, learning about strange lessons and hidden passages, and watching three children find their place in an extraordinary world. I still love the smaller details — Nearly Headless Nick’s Deathday Party, Peeves creating chaos, Filch secretly trying to learn magic, and all those little corners of Hogwarts the films never had time to explore.
But the story has grown up with Harry. The danger is no longer something waiting at the end of the school year. It’s everywhere, and the consequences are increasingly permanent. Oddly enough, the book is still incredibly funny. It can make me laugh at Ron one minute and sit in silence the next.
This time I’ve been listening to the full-cast audiobook, while also reading the book whenever I can. What an experience. The distinct performances, sound design, music and especially the pacing have brought these scenes to life. I especially enjoyed Riz Ahmed as Snape, alongside the performances for Slughorn, young Tom Riddle, Kreacher and Harry. The production knows when to let an argument roar and when to draw the sound back into Harry’s thoughts. Some moments feel closer to an exceptionally well-produced radio drama than a conventional audiobook.
I remember the films, including some of the revelations from later instalments, but the books keep surprising me with how much more they explain. Here, the memories, conversations and quieter moments give the biggest revelations room to breathe.
Hogwarts is changing, but it is still Hogwarts #
The opening immediately makes the wider world feel different. The destruction, the change of Minister for Magic, and Dumbledore collecting Harry himself all make it clear that the war is no longer confined to Hogwarts. I enjoyed Dumbledore recruiting Horace Slughorn and Harry gradually finding his feet again at the Burrow. The family conversations and the running jokes about Fleur — or “Phlegm”, as Ginny calls her — give the story some welcome warmth.
Then there’s the return to school: Harry’s surprisingly good O.W.L. results, his new position as Quidditch captain, Ron trying to prove himself as Keeper, and Ginny becoming such a strong presence in both the team and Harry’s life. The Slug Club, non-verbal spells and Hagrid’s wounded feelings at the trio dropping his subject make Hogwarts feel like a real school again. I love these moments just as much as the great mysteries.
The Half-Blood Prince’s battered Potions textbook is a fantastic idea. Harry is suddenly brilliant at Potions thanks to handwritten corrections that seem more useful than the official instructions. I kept thinking: if these methods are better, why aren’t they being taught? Hermione is understandably suspicious, while Harry becomes almost defensive of this unknown genius. The little spells, such as the one Harry uses on Peeves, add to the temptation. But the ominous “For Enemies” beside Sectumsempra should have been a much louder warning.
Learning how Tom Riddle became Voldemort #
I loved Dumbledore’s private lessons. Instead of just telling Harry that Voldemort is evil and must be stopped, he takes him through the life of Tom Riddle. We see the orphanage boy who already steals trophies and frightens other children, the Gaunt family’s obsession with ancestry, Merope’s miserable life, and Tom’s growing fascination with his own history. It feels like an investigation. Dumbledore has spent years tracking down and examining memories, some of them damaged or deliberately altered.
What struck me most was the contrast between Tom and Harry. Both had unhappy childhoods. Both discovered at eleven that they belonged to a magical world. Yet Tom saw magic as proof that he was superior and could control people. Harry found friendship, wonder and a place to belong. I’ve always felt that character comes from choices rather than bloodline, and these memories reinforce that.
The memory of Tom visiting Morfin, murdering his father and grandparents, and leaving Morfin to take the blame is chilling. Later, working at Borgin and Burkes, Tom visits Hepzibah Smith and sees Slytherin’s locket and Hufflepuff’s cup. I suspected he was cultivating contacts to seek out powerful historical objects, especially the locket connected to his own family. The cup almost seems like an additional prize. His old habit of collecting trophies is taking on a very sinister meaning. When Hepzibah dies and her house-elf Hokey is blamed, the pattern is horrifyingly familiar.
The scene where the older Voldemort comes back to ask Dumbledore for the Defence Against the Dark Arts job is brilliant. Their polite conversation barely conceals the confrontation underneath. Voldemort calls his waiting followers “friends”; Dumbledore sees through him. And discovering how long the position has apparently been cursed made me realise this wasn’t just a strange run of staffing problems during Harry’s school years.
Suspicions, romances and a dangerous school year #
Meanwhile, Draco is clearly hiding something. Katie Bell’s cursed necklace, his visit to Borgin and Burkes, his disappearances from the Marauder’s Map, the way he looks progressively more ill, and his refusal to accept Snape’s help all suggest something serious. Harry is obsessive, certainly, but I kept thinking that his suspicions deserved an investigation, even if he couldn’t yet prove them. Recruiting Dobby and Kreacher to follow Draco was genuinely clever. Their completely opposing accounts of him, with Kreacher practically worshipping Draco while Dobby despises him, are hilarious in the audiobook. And when they discover he’s using the Room of Requirement, Harry finally has a real lead. I suspected the Vanishing Cabinet might be involved, perhaps with Draco testing it before using it to transport Death Eaters. The book gives us enough pieces to form that theory without yet handing us the answer.
And Hogwarts is still wonderfully funny. Ron’s entire romantic disaster with Lavender, Hermione’s jealousy, and Harry trying to stay out of the middle are a delight. The love-potion chocolates intended for Harry are another brilliant Ron scene, although the comedy turns frighteningly serious when the poisoned mead nearly kills him. Harry saving Ron with a bezoar, and Ron later murmuring Hermione’s name in the hospital wing, gives their relationship a tenderness beneath all the ridiculous arguments. I do wish Ron had simply told Lavender how he felt instead of avoiding her.
Then there is Harry’s growing attraction to Ginny, complete with the jealous monster in his chest. Ginny’s argument with Ron about snogging, Harry’s awkward silence, Luna’s wonderfully eccentric commentary at Quidditch and her Rotfang Conspiracy advice at Slughorn’s party all had me laughing. I also enjoyed Harry pretending to give Ron Felix Felicis before the match, only to reveal he’d done nothing of the sort. Ron’s confidence was his own all along.
The Burrow at Christmas is another highlight. Fred and George are outrageous as ever; the gilded gnome wearing a tutu as the Christmas angel is the sort of detail I adore. The family clock, the dancing, and the conversations about an increasingly dangerous world make the Weasleys feel like a family rather than background characters. Harry’s confrontation with Rufus Scrimgeour is excellent. When the Minister wants Harry’s public support, Harry refuses to forget how the Ministry treated him and shows the scars left by Umbridge. He’s loyal to Dumbledore, not to whoever happens to hold office.
I found Lupin’s account of Fenrir Greyback disturbing, especially knowing Greyback deliberately targets children. Lupin’s decency makes the prejudice he faces feel all the more cruel. The party scene with the vampire Sanguini had already made me think about how inconsistent wizarding society can be in its treatment of different beings.
The Apparition lessons are a funny piece of magical world-building: twelve weeks, twelve Galleons, Twycross’s three Ds, students spinning on the spot and the horror of Splinching. Ron wishing he could Apparate like Dobby and Kreacher sums up the whole experience. And Harry finally managing to land inside the hoop feels like a genuine little achievement.
A memory worth waiting for #
The biggest breakthrough comes when Harry finally drinks Felix Felicis. Ron and Hermione expect him to pursue Slughorn directly. Instead, Harry announces he’s off to Hagrid’s, apparently having lost his mind. What follows, with Aragog’s funeral, Hagrid and Slughorn getting increasingly merry and the singing, is absolutely hilarious. The full-cast production makes the transition from comedy to something intimate and serious incredibly effective. Once Hagrid falls asleep, Harry reaches Slughorn by talking about Lily, whom Slughorn genuinely admired. The potion seems to guide the circumstances, but Harry still has to find the words.
And then the true memory. Slughorn is visibly disturbed by the subject of Horcruxes; young Tom Riddle’s calculated curiosity is chilling. Murder tears the soul, and Voldemort wants to know whether the soul can be split repeatedly — into seven pieces. Hearing Slughorn recoil from that suggestion makes the horror of it unmistakable.
Dumbledore’s explanation finally joins up things I remember from earlier books. Tom Riddle’s diary wasn’t simply a magical notebook: its destruction in Chamber of Secrets was part of the evidence Dumbledore had been assembling. Voldemort’s boast at the graveyard about having gone further than anyone towards immortality suddenly has a specific meaning. Dumbledore has already destroyed Marvolo Gaunt’s ring, which also puts his dreadful injured hand in a new light.
This is where the novel vastly improves my understanding of the films. Dumbledore doesn’t just announce what the Horcruxes are. He shows Harry how he knows, which clues remain theories, and why Voldemort would choose historically important objects. Slytherin’s locket and Hufflepuff’s cup suddenly fit a pattern. I found myself thinking about other Hogwarts founders’ possessions, Ravenclaw’s diadem, the Grey Lady and the possibility of asking Luna for help. Dumbledore also raises Nagini. Of course, assembling a list of possibilities is much easier than knowing where any of them are hidden. Hindsight can make a mystery look deceptively simple.
But perhaps my favourite conversation in the entire book is the one about the prophecy, love and choice. Dumbledore explains why Harry is different from Voldemort. It isn’t that Harry is magically stronger. Harry understands love and is capable of choosing to protect others. The conversation goes all the way back to Philosopher’s Stone: Harry could retrieve the Stone from the Mirror of Erised because he wanted to find it, not exploit it. In the mirror, he wanted to see his family. Tom Riddle, learning that he was a wizard, wanted power over others; Harry wanted somewhere to belong.
Harry finally understands that the prophecy is not dragging him unwillingly towards Voldemort. He wants to stop the man who killed his parents, just as his parents chose to stand against him. I loved hearing that realisation settle in. Dumbledore, one of the greatest wizards alive, genuinely admires Harry — not merely his ability, but his character. That relationship is so much richer in the novel.
The Prince’s spell #
Then the book shocks you again with Sectumsempra. Harry and Draco’s fight in the bathroom is a proper duel, full of dodges and counter-jinxes, before Harry casts a spell he doesn’t understand. Myrtle’s screams of murder, Draco’s injuries and Snape’s immediate healing turn the scene horrifying. For once, when Harry gets detention, I thought he deserved it. He knows he was wrong, but he remains oddly determined to defend the Prince. Hermione has every reason to be furious.
Before his detention, Snape demands to see Harry’s Potions textbook. Harry has already hidden the Prince’s copy in the Room of Requirement and borrowed Ron’s instead, but Ron’s failing Spell-Checking Quill has written his name as Roonil Wazlib inside it. When Snape asks why the book bears that name, Harry claims it is his nickname. It is such a ridiculous lie that I laughed out loud.
Harry hid the Prince’s book among mountains of forgotten possessions, marking the spot with a bust and a tiara. Earlier he couldn’t get into Draco’s version of the room; now he’s using it to conceal his own secret.
The punishment costs Harry the Quidditch final, but he returns to the common room to discover Gryffindor have won the Cup. And then, at last, Harry kisses Ginny. After all his agonising about Ron, the moment happens spontaneously amid the celebrations. I was almost as surprised by how naturally Ginny responds. Ron’s tiny gesture of approval resolves a whole book’s worth of anxiety.
The happiness doesn’t last. Trelawney casually reveals that Snape overheard the prophecy that led Voldemort to Harry’s parents. I loved Harry’s sarcastic joke about why Trelawney hadn’t seen something coming; then suddenly their conversation becomes devastating. The voice performance for Harry is phenomenal as his anger takes over. It’s one more reason why this audiobook works so well: the emotional turns are allowed to land.
The cave and the tower #
Dumbledore then takes Harry to the seaside cave. The whole sequence is terrifying. Young Tom Riddle once frightened two children there, and now we understand why Dumbledore has returned to it. The enchantments, the potion, Dumbledore’s distress and the Inferi all build a sense of dread. Harry has been learning about Inferi all year, yet in the panic he forgets how useful fire can be. Then even in his weakened state Dumbledore conjures that extraordinary ring of flame. Harry managing to Apparate them away is another reminder of how much he’s grown.
Back at Hogsmeade, the Dark Mark hangs over Hogwarts. What follows on the tower is almost unbearable. Dumbledore immobilises Harry beneath the Invisibility Cloak; Draco disarms Dumbledore and explains his mission. The Vanishing Cabinet theory is confirmed, right down to the way Draco has used the Room of Requirement to bring Death Eaters into the school. But what matters more is how frightened and conflicted Draco seems when the moment comes to kill Dumbledore. Dumbledore still tries to reach him.
Then the Death Eaters arrive, including the repulsive Fenrir Greyback, and Snape kills Dumbledore.
The chase afterwards is chaotic and gripping. Harry tears after Snape, casting spells, encountering fighting students and Death Eaters, until Snape counters the very spells Harry learned from the Prince’s book. The revelation that Snape is the Half-Blood Prince is powerful in its timing: the man Harry has despised is the same one whose intelligence he’s admired for months. And then Harry must return to Dumbledore’s body. The grief that follows feels immense.
I remember when this book came out and people were shouting spoilers about Snape killing Dumbledore. Hearing the whole sequence now, with all the buildup, makes me appreciate just how much that one notorious sentence fails to capture.
The scenes in the hospital wing are among the book’s most important quieter moments. Bill has been savaged by Greyback while the werewolf is in human form, and nobody knows exactly what the injuries will mean. Molly assumes Fleur might no longer want to marry him. Fleur’s response is magnificent: she’s beautiful enough for both of them, and his scars show his courage. I loved her fierce commitment to Bill, especially after the months of Ginny and Hermione making fun of her. It also means their upcoming wedding feels earned, rather than appearing out of nowhere as it largely does in the films.
Then Tonks’s sadness finally makes sense: her changed appearance, her altered Patronus, her unhappiness. She loves Lupin. He thinks he’s too old, too poor and too dangerous for her, but the people around him challenge that belief. Coming straight after Fleur’s declaration, the scene drives home the same idea: love isn’t cancelled by injury, fear or the prejudices of other people.
McGonagall wants to know what Harry and Dumbledore were doing together. Harry refuses to say. He respects her enormously, but his promise to Dumbledore remains his promise. Harry finally tells Ron and Hermione what Dumbledore had been investigating, and about the false locket bearing the initials R.A.B. I know from the later film who those initials refer to, but I tried to put that knowledge aside. Without hindsight, three initials are hardly an easy place to start, even when the relevant family history has appeared in an earlier book.
The whole world comes to say goodbye #
And then Dumbledore’s funeral. I honestly don’t know whether I can do the audiobook production justice here.
The bells, the procession, the people arriving from across the wizarding world, the Hogwarts ghosts and magical creatures, and Hagrid carrying Dumbledore’s body while sobbing — even Grawp is there. Familiar faces from throughout the series return, including people Harry likes and those he cannot stand. It feels as though the whole world Rowling has built has gathered in one place.
But the music is what stayed with me. The merpeople’s strange, sorrowful song; those beautiful, almost a cappella voices; the sense of something otherworldly that Harry cannot quite understand but knows is mourning. It made the hair stand up on end, without being unpleasant. Then the music gives way to silence and the funeral address. The pacing is phenomenal.
Harry realises that the last of his great protectors has gone. His parents, Sirius, and now Dumbledore. After spending this book becoming closer to Dumbledore than ever before, that thought hurts.
I loved Harry’s conversation with Ginny after the funeral. It’s so much more mature than their earlier awkwardness. Harry believes he has to end their relationship to keep her safe, and Ginny understands what drives him even though it hurts. I don’t entirely agree with Harry deciding what protection means on her behalf, but the scene is moving precisely because neither of them is being silly about it. And discovering Hermione had advised Ginny to live her own life rather than wait around for Harry made me smile. Clever girl, Hermione.
Scrimgeour tries once more to question Harry, and Harry still refuses to be used or intimidated. It recalls the scars he showed the Minister at Christmas and his refusal to become the Ministry’s public mascot. With Dumbledore gone, his loyalty somehow feels even stronger.
Finally, Harry tells Ron and Hermione that he isn’t planning to return to Hogwarts for seventh year. Hermione struggles with the idea of not going back to school — understandably! — but neither she nor Ron is prepared to let Harry undertake the mission alone.
And Ron, wonderfully, is basically saying: we’ve got your back, but Bill and Fleur’s wedding first.
That’s Ron Weasley. Incredibly funny, fiercely loyal, occasionally hopeless, and devoted to his family. I love him in the books. He isn’t merely the comic relief; he’s Harry’s brother in everything but blood. His instinct to stand beside Harry without making some enormous speech is one of the most moving things about the ending.
I finished the book thinking about how much has changed. The first stories were full of the wonder of discovering Hogwarts. That wonder is still here, hidden in the jokes, the ghosts, the lessons, the friendship and the strange everyday magic. But now everything is more serious, more intense, and sometimes devastating. Half-Blood Prince has stayed with me, and I suspect it will for a while.
