Wrath

All I see is red.
Blood.
Pain.
Rage.
It consumes me.
The moment he took her, wrath invaded my soul.
I only have one purpose. 
End him and take back what's mine. 
Love isn't always clean, and wrath is the deadliest sin.

Wrath is the first book in The Deadliest Sin series about organized crime in Philly and Chicago. This series is best read in order beacuse the stories occur chronologically and each sin builds on the events of the previous one.
