Inferno (Devil Chaser's MC 1) by L. Wilder

Tessa is a school teacher and single mom starting a new life in Paris, TN. Romance is the last thing on her mind.

Bishop is the leader of the Devil Chasers’ Motorcycle Club, and a single dad trying to rescue his son from sins of his father. He doesn't have time to add a woman into the mix.
Bishop's past won't let go, and soon Tessa is swept up in the powerful, intense biker's world - and all the danger that brings. How hard can she hold on?
