Mr. Penumbra's 24-Hour Bookstore
I loved this story. It was so interesting and smart. About a third of the way through I knew where the group would find answers, but since I wasn't exactly sure what the answer they were looking for was going to be, I was hooked the entire time. I like the characters and how everything wove together to make a really great read. Also, the book cover glows in the dark!
