I need to forget our fling, but Sarah calls me when her life is in danger. I'll help her. But who will rescue me?

Book Six in the Hell Raiders MC Romance series continues Crank and Sarah's story, which began in Fabio's Remorse.

Crank:

I can't get Sarah out of my mind. When she calls me, terrified for her life, there's no question. I'm there in a heartbeat.
The plan is to take care of her problem and walk away. I would destroy her. She's too good for an outlaw biker. Even if it kills me, I have to let her live the life she's supposed to have. Except I need her like I need air. I need forever with her. And I'm too much of a f***ing coward to take it…

Sarah:

It was a quick fling for him, and I have to accept that. But when I'm in big trouble, who do I call? Crank. I don't know why, except he's the only one I ever felt truly safe with.
He comes to my rescue, and I fall even harder for him. He's so…Intense. Just as I start to believe we can make a real future, he grows cold and distant. Devastated, and with my life in chaos, all I can think is…Who will save me from Crank?

Can they rescue each other?
