My 9 and 12 year old daughter's absolutely loved this book! I read it aloud to them. They always begged me to read more. When we were on the last 3 chapters I read the third to last one and put it down. They had to know what happens next, so they took it upon themselves to continue the reading. I hand-sewed on a project while they finished reading the book aloud. We've been discussing the book all along. We even had a list of suspects on our board. We hope they make this into a movie!
