There’s pretty much only one rule when you’re a guy. Don’t be a douche. Turns out, the fastest way to break that rule is to fall for your best friend’s sister. Ava’s brilliant, sharp-tongued, gorgeous, and five years younger than me. She’s the sexual equivalent of running with scissors. In a word, she’s dangerous. And completely off-limits. Falling for her could ruin everything. Yet I can’t seem to stop, even when her company is threatened by a lawsuit, and my promotion hinges on representing the opposing client—and winning. I can’t see a way out of this mess that doesn’t end in a broken friendship, a broken heart, or a ruined career. I may have broken the bro code when I fell for Ava. But do I have the balls to handle what comes next?
