Miles wants to repay Pierce for saving his life. Pierce shouldn’t see him as anything but a convenient hookup… and he sure as hell shouldn’t get involved in Miles’s doomed quest to get his brother out of a rival street gang. He shouldn’t do a lot of things, but life on the streets isn’t about following the rules. Besides, he’s sick of being abused by the Vice family, especially Mr. Vice and his power-hungry goon of a son, who treats his underlings like playthings.
So Pierce does the absolute last thing he should do if he wants to keep breathing—he leaves the Vice family in the middle of a turf war.
