Query: My favorite book ever!

I read...a lot, actually. I have a nook, and a kindle, and bookshelves full of paperbacks. I can't go to sleep at night unless I read at least a chapter. Out of all the books that I have read, Hidden Places is one of my all-time favorites. The characters are so complex and mysterious. You can't put the book down as you start to turn each page and the characters begin to unfold and the story slowly comes together. I highly recommend it!
