Instant Attraction by Jill Shalvis

Accountant Katie Kramer is a quintessential good girl - working hard, recycling diligently, all the while trying to ignore the feeling that she doesn't fit in anywhere. That's all she wants. Well, that - and amazing sex, and the kind of daredevil escapade she can look back on when she's crunching numbers in a dusty cubicle. Which explains why she just took a job in Wishful, California, working for Wilder Adventures and Expeditions. Waking up to find a magnificently built stranger towering over her bed - that part defies explanation...
After wandering the planet for months following a life-changing accident, Cameron Wilder has come back to the only home he knows. Under other circumstances, he might be thrilled to find a gorgeous woman sleeping in his cabin, but now, while he'll risk his body taking clients on adrenaline-drenched excursions, his heart is off limits. Still, Katie's killer smile triggers something deep in his gut... among other places. Showing her how exhilarating it can be to stop balancing her life as if it was a checkbook is the biggest rush he's ever felt - and an adventure Katie's wishing would never end...
