Striker (No Prisoners MC 1) by Lilly Atlas

The MC can and will eliminate any threat against Lila, but what if they—and the man she's falling for—are the reason she’s in danger?

Dr. Lila Emerson is finally free of the shadow of her politically connected family, with her new job in a small town Emergency Room. But her new peace is shattered when she encounters the dangerous, but compelling Striker. He's everything she should stay away from, but all she craves. And since he keeps turning up in her ER, he's hard to avoid.
As Vice President of No Prisoners outlaw motorcycle club, Striker is no stranger to violence. But when it touches the pretty doctor he wants in his bed, he'll do anything to keep her safe. When Striker and Lila are thrust together, sparks fly and passions ignite. Before long they find themselves entangled in a relationship neither saw coming.
