Wrong Bed, Right Guy (A Come Undone Novel) by Katee Robert
Prim and proper art gallery coordinator Elle Walser is no good at seducing men. Heck, she's been throwing hints at her boss for months, but he's completely clueless. Desperate to escape her mother's matchmaking efforts, she comes up with a plan—buy some lingerie and climb into her boss's bed. The plan goes brilliantly…until she accidentally seduces a sexy stranger instead. Bad boy nightclub mogul Gabe Schultz just had the best almost-sex of his life. Too bad the smoking hot blonde thought he was his brother and bolted before he could finish what they started. Though her holier-than-thou attitude puts a serious damper his mood, Gabe's never been one to give up on something he wants. And he wants Elle. But does a man who lives on the dark side really have a chance with a proper lady?
