Seductive Mines — M.L. Rigdon

Phil has a problem. Or two. Now that she has her dream guy, Rod, aka R.W.Chaucer, one of the rich and famous, he can't shake his previous girlfriends and gets himself kidnapped. Then her best friend falls face-first for Rod's bodyguard and she disappears. On top of that, an industrialist, out to get Rod's mother, decides he wants the treasure Phil hopes to find when she goes searching for ancient Inca gold mines, because the industrialist knows that what Phil's really hunting isn't gold.
