Thereโs pretty much only one rule when youโre a guy. Donโt be a douche. Turns out, the fastest way to break that rule is to fall for your best friendโs sister. Avaโs brilliant, sharp-tongued, gorgeous, and five years younger than me. Sheโs the sexual equivalent of running with scissors. In a word, sheโs dangerous. And completely off-limits. Falling for her could ruin everything. Yet I canโt seem to stop, even when her company is threatened by a lawsuit, and my promotion hinges on representing the opposing clientโand winning. I canโt see a way out of this mess that doesnโt 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?
