Promise Boys is a murder mystery revolving around three teens accused of murdering their Principal. In a bid to clear their own names they come together with some allies to figure out what really happened. I thoroughly enjoyed this book and thought it was very well written. I liked that the first half had a closer look at JB, Trey and Ramon through character testimonials and then their own view of the day before and day of the murder. It meant that by the second half I really cared about finding out who the real culprit was. The school system itself was shocking - no talking, responding to signals to leave class and teachers who mostly seemed to dislike the pupils. It all added to the intensity of the mystery though as there were so many suspects. A fast-paced YA thriller!
