The members of Sin City MC never leave before all the cards are played. I have one job. Be the vault. Protect the club's secrets and help fix the screw ups, all while lining the MC's pockets. But someone messed up and got us on the police radar. Now, the club's in trouble and I'm busting my ass to keep our hides out of jail. We can't risk another mishap, so when one of our guys stirs up trouble with the new girl, I step in. Or rather, fall in. I didn't want her. Didn't need her. Didn't have time for her. But Trinity snuck into my heart and blew up my life in ways I'm still reeling from. My job now... Pull the trigger and raise the Caliber. Caliber is an interracial romance.
