In Too Deep by Taryn Belle

Welcome to the Caribbean’s secret playground for the rich and famous
Where your wickedest sexy deeds are almost a secret…
On a tiny tropical island teeming with the rich and famous, Nicola Metcalfe is an unrecognizable nobody. Which is just about perfect. Her life in LA—including her teaching career and the sleazy tabloid scandal that capsized it—has been replaced by sun-kissed beaches, deep blue waters and a new job as a scuba instructor. Hell, Nicola could even forget about her nonexistent sex life…until she saves Alex Stone’s life.

Alex might be the worst scuba diver in the ocean, but every inch of him is beautiful, firm-bodied perfection. The kind that jolts about a zillion megawatts of pure, crackling sexual tension straight to Nicola’s naughty bits. Maybe it’s something. Maybe it’s just for tonight. But whatever it is, Nicola wants it. Badly.

After all, Alex isn’t staying long enough to discover who she really is—or what she did.
Not long enough to do anything other than give in to the intense, insatiable craving that threatens to drown them both.
And definitely not long enough for Nicola to discover that the guy she’s falling for might just be responsible for ruining her life…
