Book 2 of the Souls Trilogy
 
"After a cult tried to sacrifice me to their wicked God, I went on the run, doing whatever was necessary to survive. Until a demon offered me a deal: give him my soul and he'll help me claim the vengeance I seek. Blood will be spilled, and the monsters I once ran from will soon be running from me. But damning my soul was just the beginning - it's my heart the demon wants next."
