Acceleration by Graham McNamee

Acceleration by Graham McNamee is about 17 year old Duncan. He's been having a hard time since last summer, when he witnessed a girl drown and couldn't reach her in time. He feels like it's his fault. Ever since, he's had bone chilling nightmares about that day, and has even lost his girlfriend due to his over-protectedness. Now, Duncan is working at the lost and found in the Toronto subway system. Bored one day, he picks up a leather-bound diary that someone left on one of the trains. What he finds both terrifies and intrigues him. There are journal entries, notes, newspaper clippings, and drawings of all of the terrible things he's done - setting fires, torturing animals - and, worst of all, plans to take it to the next level. Duncan finds detailed plans for harming a woman. Seeing this as his opportunity to make up for not saving the drowning girl, Duncan does his best to try to solve this mystery: Who does the diary belong to? Is he really planning to kill someone? Can he be stopped? With the help of his best friends Vin and Wayne, Duncan does his best to save the victims and stop the madman.

This was a suspenseful story. It was really interesting to see how the author unfolded the events with the drowning, the diary, and Roach (Duncan's name for the serial killer). I especially enjoyed the action sequence at the end when Duncan confronts who he suspects is the owner of the diary. This book does have some violence, content, and language, so I would recommend it for more mature readers.
