How did I find myself sharing a tent with my obnoxious—albeit gorgeous—neighbor, Isabella Romero? It all started with a stupid bet.

All I had to do in order to win was something unpredictable. (Which my brother thought was impossible for the ever-boring David Windell).

Well, I showed him . . . by booking a trek in the Andes Mountains to see Machu Picchu.

When the brochure for the expedition mysteriously appeared on my front porch, it was like fate interceded: I could win the bet while simultaneously getting a vacation from my irritating neighbor.

Two birds, one stone.

Except, it turns out that was Isabella's brochure . . . and she booked the same trip.

So here I am, stuck sharing a tent with the woman who drives me crazy—and makes my heart race like never before.
