4.5 STARS. I was in the mood to read a thriller so i took this book and i'm not disappointed! I loved the setting in a high school, and the psychological side of it all -adults hunted by their dark pasts, not capable to move forward-, i found Thomas a very well-written and interesting character. The plot-twists were insane, i mean i wasn't expecting them and it made this story very intense and gripping. As a result, i read the book in two days, and i couldn't put it down.
