Half-Blood Prince marks Harry Potter's key emotional maturation, completing his transformation from the angry, petulant teenager of book five, into a strong, young man, aware of his destiny and able to bear its burden. The tragic death of Sirius Black, who is Harry's only friendly relative, is widely regarded as having been a major catalyst responsible for this change.
Harry also shows more willingness to bond with those around him, particularly Dumbledore, with whom he cements a close mentor-student relationship. His friendships with Ron and Hermione have also developed — he does not isolate himself as he did in his fifth year. Rowling points out the strength of Harry and Ron's bond of friendship several times, and Harry and Hermione's friendship has also developed to the point where they actually laugh and joke together - a development from Harry's opinion in book four that hanging around with Hermione was "just not the same" as hanging around with Ron. Rowling says that by this point, Harry has adopted Ron and Hermione as his family.
Harry shows great emotional development, particularly in the field of personal relationships. By the end of the book, Harry has matured so much that he feels ready to take on his burden of destroying Voldemort. He is now a more active hero, prepared to leave behind his childhood and actively seek out Voldemort and try to kill him, rather than simply trying to survive or hide behind a shield carved by his protectors.
This is the first novel in which we see a Slytherin who is presented in a generally positive light — Horace Slughorn. Slughorn — though he possesses the Slytherin attribute of an attraction to power — is far from a Death Eater. In fact, he seems genuinely appalled and ashamed and insulted by the unintentional role he may have played in Voldemort's rise to power, and though he expresses surprise that Muggle-born wizards and witches can be as powerful as 'pure-bloods', he does not discriminate against Muggle-borns — Lily Evans being one of his favourite students. Though Slughorn is not always likeable, and tends to have his favourites, he appears to be an overall positive character.
In some ways, the novel can be considered a reflection of the second book of the series, Harry Potter and the Chamber of Secrets. Both stories feature a book that 'talks' from the past, similar characters and objects, and a threat with the potential to close Hogwarts. This is no coincidence. J.K. Rowling has stated that Harry Potter and the Half Blood Prince was the working title for the earlier novel, and many plot elements that eventually appeared in the later novel were a part of early drafts.
