Query: Great Book, Must Read

This book was great. This is the first book of his, but i'm sure it won't be my last. I really enjoyed most of the book. I wanted to know more about how Melanie's dad tortured her and why he did it. The plot was great. I wanted to keep reading, I even read it as I walked home from school. This is pretty hard to do. The only thing I disliked about this book is the ending. I like books that end differnt than what you expect. This was not one of those books. I knew the whole time that Melanie was controling "The Door to December" I really enjoyed how this book was not really far fetched. You could see this happening some time in the future.
