Promise Me (Defiant Motorcycle Club 2) by Cora Brent

Promise Talbot needs to escape. Forced into a polygamous marriage to a sadistic man, she grabs a desperate opportunity to flee his clutches. And falls into the world of the Defiant Motorcycle Club.

Grayson Mercado seethes with the injustice of a long imprisonment for a crime he did not commit. Finally free, he is trying to make a life among his new brothers. Everything changes when a battered young woman approaches him, begging for help.
Promise and Grayson couldn’t be more different.
But the collision of passion and danger will spark a love written in their fates.
