Chaston, I moved your request to the "Unsolved" folder because you're looking for a specific book.

Please add details to the topic title/header (e.g., description of book but no spoilers, genre). Click the "Edit" link at the top beside the title (if you're on a desktop computer). This will help people help you. Good luck!
