Harry Potter and the Dealthy Hallows is the seventh and final book in J.K. Rowlings Harry Potter series. Voldemort is continuing to accumulate power and it is up to Harry, Ron, and Hermoine to find the remaining Horcruxes to defeat him once and for all. When the Death Eaters descend upon Hogwarts, it leads to a battle that will affect the future of the wizarding world forever.
Harry, Ron, and Hermione have to drag Fred’s body out the way, and Harry can’t permit himself to grieve. The castle is under serious attack, and the last Horcrux to be destroyed is Voldemort’s snake, Nagini.
Harry allows himself to go into Voldemort’s mind, and discovers that he’s in the Shrieking Shack. They throw on the Invisibility Cloak and weave their way through the battle. They make it to the Whomping Willow and head into the tunnel that leads to the Shrieking Shack.
While they are in there, they hear Snape talking with Voldemort. Voldemort wants to know why the Elder Wand won’t work for him like it’s supposed to. He can’t do the extraordinary magic that he thought he’d be able to, and he blames Snape for this. Because Snape is the one who killed Dumbledore, Snape is the wand’s true owner. He therefore must kill Snape in order for the wand to work properly, andhe does this immediately, with no remorse, setting Nagini on Snape. Voldemort leaves the shack and the three of them rush in to see Snape dying. Snape, however, gives Harry one last thing before he is gone for good: he gives him his memories. After that, Snape tells Harry to look at him. Snape stares at Harry's green eyes before his own eyes fade away.
