This is going to be a short review because I really didn't like this book. I liked that it was short, I was able to read it all in one night and honestly if it had been longer, I probably would have given up on it. The first thing that struck me was the awkward dialogue. It sounded so forced. I thought for awhile that maybe Joe had some sort of mental disorder and when it was finally explained that he had ADD, it made a little more sense. But really, everyone in the book (with the possible except of Cecily) didn't seem quite right. I've never read a book before with so many - how do I put this? - psychologically stressed characters.
One star. Don't bother. If you're really curious, borrow a copy from the library.
