Title is too hard to translate

Harry will return to the home of his Muggle relatives, the Dursleys (whose cooperation has been requested by Albus Dumbledore), during the school holiday. The magical protection Dumbledore arranged, which requires Harry to have a home with them, is set to expire on his upcoming birthday, when he comes of age.

Harry plans to visit the remains of his parents' home in Godric's Hollow. Ron Weasley and Hermione Granger plan on accompanying him on this trip.

Bill Weasley and Fleur Delacour plan on getting married in August. Several of the main characters have been invited.

Bill Weasley has been bitten by a werewolf (Fenrir Greyback); however, Fenrir was not fully transformed (he was not bitten on the day of a full moon), and we have yet to see the full effect of the bite. So far it has been said that Bill has merely developed a taste for steak cooked very rare.

It is unclear what will happen to Hogwarts after the attack on the school at the end of Half-Blood Prince, but Harry has said he will leave school to continue his battle against Voldemort. If the school reopens, replacements will be required for Severus Snape (Defence Against the Dark Arts instructor and head of Slytherin house) and possibly Minerva McGonagall (Transfiguration instructor, head of Gryffindor house and deputy Headmistress) in the event that she becomes Headmistress.

Harry must destroy all of Voldemort's remaining Horcruxes before Voldemort can be defeated. Dumbledore believed there were a total of six, and that two so far have been destroyed (the Gaunt ring and Riddle's diary).

There is no explanation at the end of Half-Blood Prince as to the true identity of the mysterious "R.A.B.", who claimed to have stolen one of Voldemort's Horcruxes, a locket, with the intent to destroy it, while replacing it with a fake locket, later recovered by Harry and Dumbledore Rowling said Regulus Black was "a fine guess" for R.A.B.'s identity in an interview.

The true loyalty and motivations of Severus Snape have been unclear throughout the series. At different points in the series, Snape's actions have either conflicted with his stated intentions or with his previous actions. Because of the contradictions in his behavior, Snape remains a potential wild card. This is in contrast to the other main characters who have very clearly chosen allegiances.

It has not been explained why, when Dumbledore heard that Voldemort had used Harry's blood to resurrect himself, Harry sees a "gleam of triumph" in Dumbledore's eyes. Rowling has said that this is still "enormously significant".

It is still unclear if Sirius Black, Harry's Godfather, is indeed dead or just trapped behind the arch. (He was not hit with the "Killing Curse" as shown in the film adaptation of Harry Potter and the Order of the Phoenix)

No one was credited with performing the magic involved with the spectacular flaming raising of the white marble tomb of Dumbledore. Whether or not this is significant taken along with Scrimgeour's hasty assertion a few plot moments later that "He's gone... not even Dumbledore can return from the—" creates a slight opening to hopeful speculation. However, J.K. Rowling has repeatedly quashed theories that state Dumbledore is alive.
