Query: Lost Boy - did you lose your mind?

I just finished this book and I am pretty disappointed. The idea behind the book was pretty fascinating, so this book could have been great, but it was just so dull. As I was reading it, I kept asking myself, ok so when is something going to happen. It took forever for anything interesting to build up. I think I was 3/4 through the book before it started to get interesting, and then at the end, I felt really cheated.
