I started this book a year ago, misplaced it, found it, misplaced it again and finally finished it. Kept misplacing it because I would take it everywhere with me to read, or fell asleep with it and lost it under my bed.
Only minor comment is that because I'm an adult, the idea of FBI working this closely with teenagers on a case this serious had me suspending my belief anytime the age of the characters were brought up (but I would have ate it up as a teen). If they would have been just a couple years older I wouldnt have blinked about it, BUT that being said - I'm still glad it took me awhile to finish it because now I dont have to wait as long to read the sequel when it comes out!
