Being stuck together in a redwood forest can really bring your inner animal out . . .

The last thing Gayle Richards wanted was to spend days alone in a cabin with Nolan Hersch, fellow professor and macho loudmouth. How could she observe the animals' mating habits alongside a man who made her blood boil…and not just in anger? The only thing more frustrating than Nolan's opinions on male sexual superiority was how much he made her want to rip his clothes off.

Well, the thin air in the mountains must have gone to Gayle's head, because she sets up a challenge: three days to prove who's more insatiable in bed. With Gayle and Nolan making their best efforts to wear each other out, this may just be the sexiest experiment of all.
