they are nothing like Lord of the Rings

Tolkien - another man in severe need of an editor.

skaffenAmtiskaw: Wikipedia has a plot summary. The key spoiler points are (highlight amazing sortof inviso-text to read): None of the three main characters die. There is a denouement where we learn that Harry and Ginny have three children, all enrolled in Hogwarts. Dumbledore is indeed dead at Snape's hand, but at Dumbledore's request - he was already dying and the "murder" served to reinforce Snape's position with Voldemort. Voldemort dies, as does Snape, Mad-Eye Moody, Remus Lupin, Tonks (after marrying Remus and having his baby), Hedwig, Dobby, Bellatrix, Crabbe, Malfoy Sr., Fred and maybe a couple others I don't recall.
The Hallows are three powerful magical items, a wand, a stone of resurrection and a cloak of invisibility, the same one Harry has had for some time. They're kind of a red herring.
