One Mark by Nikki Kardnov

Lola’s got crap taste in men. It’s a family curse, really. So she’s come up with a new rule for her dating life: do not sleep with men you like. Just in time, too, it turns out, because she’s recently met Thorin Blackwell—a hot as hell djinn with a face like a god and abs to match.
But nope, she’s safely friend-zoned Thorin. As long as they stay friends, Lola has nothing to fear. No drama. No betrayals. And certainly no broken hearts.
Thorin has his own reasons for keeping Lola at arm’s length. She’s vibrant, gorgeous, funny…and exactly the kind of woman he can never have. Monsters like him don’t get a happily ever after.
But when Thorin’s past comes back to haunt him, Lola is dragged into the center of a war between two of the most powerful djinn clans. Every wall will be torn down as they’re thrust together in a fight for their lives…and their hearts.
