It wasn't him after all...

Lillian, a 15 year old girl who lost her dad. No one knows how he died. Not even Lillian herself. It's exactly 2 years since he died. She walked into the school and all the eyes were on her. She couldn't take it anymore. She runs to the bathroom and finds the school cleaner sitting with a knife stabbing her best friend. She and her other best friend Aspin (also 15 years old) need to figure out who he is, and find out where he is hiding. Because he wasn't seen outside of school. And since Lillian found him stabbing he isn't seen in the school either....... Who is Reed?
