The Devil’s Own by LL Meyer

Alejandro:
I always knew we were a bad idea. Sophie and I are from different worlds. In theory, her expectations of me aren’t unreasonable; equality, respect, and the truth – always the truth. But in reality, a man in my position has secrets to keep, impossible decisions to make, and a reputation to uphold. All of it for her own good.
But whatever our problems, she’s mine. If she ever tries to walk away, I don’t know what I’ll do. Having to pin my mariposa down wouldn’t be pleasant for either of us.

Sophie:
I knew it wasn’t going to be easy. Making a life with a man as stubborn and overbearing as Alejandro would be challenging on a good day. He’s used to giving orders and having them obeyed, but I’m not one of his men. If we’re going to make this work, concessions have to be made on both sides – not just mine.
Despite our differences, there’s one thing holding everything together . . . we love each other. Desperately, deeply, irrevocably. Forever . . . or until one of us breaks.
