No Mercy (Phantom Riders MC 2) by Tory Richards

Club trouble won’t keep Rock from bringing his son and Allie home.

Rock’s the VP of Phantom Riders MC. Dangerous. Unpredictable. Ruthless. A killer who’ll stop at nothing to keep what’s his. And he wants Allie and their son.

Allie had given Rock her virginity, and then ran away when she got pregnant. Seven years later he shows up at her door, demanding his son, and claiming her.
