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?
