I was going to post this as a comment on Megan's LiveJournal, but I figure it could be put to better use here. It works much better if you understand that the name of the new Harry Potter book is Harry Potter and the Deathly Hallows. (SPOILER WARNING!)
Deathly: 1. Of, resembling, or characteristic of death: a deathly silence. 2. Causing death; fatal.
Hallow: 1. To make or set apart as holy. 2. To respect or honor greatly; revere.
Synopsis: Something cool happens at the beginning of the book, and then Harry just kind of dicks around for about fifty chapters. Things get cooler at the end, though, as Ron, Hermione, and Harry have a threesome, Tonks writes long, sad posts in her Wizards' LiveJournal, Snape says "BTW I'm the Deathly Hallows," and Harry Potter once again has to get someone else to rescue him. In the end, it is revealed that Voldemort's spirit is hiding inside the necromantically reanimated body of Dumbledore, and so, Harry must kill Dumbledore one last time. (SPOILER WARNING!) Dumbledore dies.
In conclusion, there are many fantasy novels better and less predictable than the Harry Potter series. Like China Mieville. Assuming that you ignore the endings of all his novels, which are terrible (possibly because he is a Marxist).
