You know you are in a Jasper Dent novel when:
You open the book, and your heart drops to your knees.
One of the characters is covered in blood. No, more than one of the characters is covered in blood.
Someone has a knife.
Jazz is in peril. Connie is in peril. Howie is in peril.
Howie is bleeding.
There is a coded message from a serial killer.
You are playing a game, but you don't know you are playing a game. The penalty for losing is death.
You were just slapped so hard with a plot twist that your jaw hurts and you can't breath.
Well played, Mr. Lyga. Well played.
