All the Rage: A Repairman Jack Novel, Book 4

Can you imagine a new chemical compound, a nonaddictive designer drug that heightens your assertiveness, opens the door to your primal self, giving you an edge wherever you compete, whether on the street or the football field, in a classroom or a boardroom? Wouldn't you be tempted to try it...just once? What happens if it releases uncontrollable rage and makes you a killer?
