Castle of Kings by Betty Shreffler

Jake F*cking Castle
When he walks into a room, he owns it. He consumes my very breath and melts my delicate little panties. From the moment he set eyes on me, he decided I was his. No one – not even my brother, Nix – was going to tell him otherwise. It doesn’t matter that Nix is President of the Kings MC Club. Jake wants what he wants, and he’ll set out to get it, whatever the cost.
Jake may be an arrogant asshole, but there’s no denying the hold he has over me. His fierce, carnal need to make me his, and his alone, is a snare I can’t escape. And truth be told, I don’t want to.

But when my life becomes threatened, Jake Castle is the only man my brother trusts to protect me. He knows Jake will do anything to keep me safe.
