The kid won't leave him alone and wants nothing more than to be his friend. On a school trip to Hawaii, he learns about a devastating secret that one of his classmates who fell down the stairs and broke their neck--wasn't an accident. Someone deliberately pushed them down the stairs. Worse. Other classmates know about it and are keeping it a secret. Sasuke is thrown into a world where he knows this terrible secret and can't figure out who to trust, who not to trust, and whether or not he should tell what happened or not. Secrets and games and lies oh my!
