Why 319? by Mark Love
This book grabs your attention almost from the start. Once you start reading, it is hard to put down. The settings and characters are very real and I found I had to keep a bright light on and the doors locked...just in case!
The plot centers around a serial killer that leaves all the bodies in room 319 and taunts the detective on the case by writing 'Why 319?' on the wall. There are plenty of twists and turns as you read and I think you will find yourself thinking you might have an idea of where this is going only to find it went where you didn't expect. I think you will enjoy it.
