Bro-Code Law 676: You never-under any circumstances-get involved with your best friend's little sister. I messed up-big-time. Two strangers in a foreign country, we said hello. Hello turned into a kiss. A kiss turned into a rendezvous. And a rendezvous turned into more than I'd ever imagined. But her unruly golden curls and beautiful body hid an important detail-he's my mouthiest billionaire best friend's forbidden little sister. Fact: I knew not of my crimes. More important fact: I know now, but even though I know I'm playing with fire, there's no way I'm stopping. I can't leave her alone. Question: What do you do when you fall for your best friend's little sister? More important question: How long can you keep it a secret before it all goes up in flames?
