The book starts with Avery who is just a toddler, wondering where her brother is. 
 And then we jump 11 year ahead... 5 Teenagers wake up with a blindfold covering their eyes, a van taking off and them having no recolection of how they got there, where there is and who they are as much as they lives beyond this exect moment. 
 After taking off the blindfold, they only saw the van leaving and realized they were all wering the same clothes and discovered a map in their pocets with a "X" marking a spot of each of their homes. 
 So after each going home, they have to find answers to 5 questions which will explain everything: 
 - Who abducted them? 
 - Why can't they remember anything? 
 - Why return them now? 
 - Who is Max and 
 - Where is Max? 
 Searching for these answers is basicaly the entire book. 
 Lucas and Scarlett follow clues that will bring back memories of their previous life until all their questions are answered in the most unsatisfactory way ever. 
 And I was like 
 What I didn't get was why we only got Lucas's and Scarlett's POV and not every kid from the "Leaving" trying to sort themselves back into the lives of their families. 
 All in all the book had me on edge till the end guessing who's behind in all this and if the reveling would be written differently and the reason behind the abduction would be a more "dark" reason, this book could be a 5 Star. 
 Still 3.5/5 Stars
