Betrayal by Jamie Garrett

I can never have her, but I’ll do whatever it takes to keep her safe.
I never had a real family. Not one you could count on to have your back, no matter what. David, my best friend and fellow solider, was the only person I trusted. Until the day I got him killed.
Now the Steel Kings MC are my family, and my life. As their Sergeant of Arms, I keep the peace and pay my penance. That’s all I deserve.

There’s just one complication. Cassie. My best friend’s widow, and the woman I’ve loved since the moment I laid eyes on her. I watch over her from a distance. She’s off-limits, always has been. One hot night with her writhing underneath me doesn’t change that.
But then I found out her secret. Someone’s been leaving her notes, following her. I can’t let myself fall for her, but I’ll protect her with my life. You can count on that.
