Thereâs pretty much only one rule when youâre a guy. Donât be a douche. Turns out, the fastest way to break that rule is to fall for your best friendâs sister. Avaâs brilliant, sharp-tongued, gorgeous, and five years younger than me. Sheâs the sexual equivalent of running with scissors. In a word, sheâs dangerous. And completely off-limits. Falling for her could ruin everything. Yet I canât seem to stop, even when her company is threatened by a lawsuit, and my promotion hinges on representing the opposing clientâand winning. I canât see a way out of this mess that doesnât 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?
