Ruin My Life (Nasty Bastards MC 1) by Hayley Faiman

Both of them are mine. I will protect them with my life. Nothing will ever touch them again. Twenty years old, and her life is in ruins. Completely and totally ruined. At least that's how it feels. She's penniless, jobless, a single mother with a car that is on its last leg—rattling its way into the mechanic garage. She runs toward a stranger in an effort to save herself.

Bowie only cares about partying, cars, motorcycles, and the club that he calls family. He doesn't do complications and especially doesn't do relationships. Free and easy is the way he lives his life, and he likes it like that.

When she walks into the mechanic garage, the entire club turns upside down.
