I found out my husband of three years had cheated on me and his mistress is the one who told me—because he didn’t have the balls to do it himself. I move out and get a new apartment, a job as a bartender, and try to move on with a broken heart. I wonder where it all went wrong, if I hadn’t been enough for him, if I’d been stupid for marrying him in the first place. I’m at work one night when he walks inside—the most beautiful man I’ve ever seen. He sits at the bar and a forest fire burns between us. I was depressed the moment before he entered, but the second I look at his blue eyes, I forget the dumpster fire that my life has become. I invite him back to my place and it’s the most passionate night of my life. I expect to never see him again. I just want him as an anti-depressant—but he wants me all to himself. I just got my heart ripped out of my chest so I want something easy and no-strings-attached, but he wants all the strings because he’s hooked. I don’t get much of a say in the matter, and that’s not surprising when I learn why—because he’s the Butcher. The crime lord of all crime lords, the boss that overshadows all of Paris, that makes everyone abide by his rules—or pay. And now I’m his.

These are the tales society whispers about but never dares to speak aloud: the aching pull of step-parents and step-children, the dangerous heat of family secrets, and the kind of love that thrives in shadows. From scorching heterosexual passion to steamy lesbian and gay encounters, every flavor of forbidden ecstasy awaits. Here, rules are shattered. Hearts betray reason. Characters surrender to the raw, uncontrollable urge to touch what they shouldn’t, step-fathers, step-mothers, blood-bound temptations, and every wicked variation in between. This is not gentle romance. This is wild, sinful, unapologetic lust wrapped in love. A dance on the razor’s edge between control and chaos, guilt and surrender. Between the crushing weight of sin and the sweet sting of redemption, these lovers become entangled in secrets, temptation, and pleasure so intense it borders on madness. Because sometimes the most dangerous thing isn’t the sin itself…
