Just Try Me... by Jill Shalvis

Adrenaline junkie Lily Peterson is no stranger to taking chances. She's been there, hiked/rafted/skied that. But that was before an accident nearly put her out of commission for good. Now, after months in physiotherapy, this former firefighter has a new motto: look before you leap. It's not as much fun, but it works. Still, it's killing her that she has to start all over again, more slowly this time. But she's going to do whatever it takes. After all, her latest job guiding a simple hiking trip through the Sierras hardly qualifies as risky. That is, until she looks at hiker Jared Skye -- and wants to leap into his bed. And if she's lucky, he'll take things slowly, too .
