Holding Out by Serena Bell

His friend’s little sister has just asked him for a BIG favor. The trouble is, once won’t be enough … for either of them.
The answer has to be no, of course. No way Griff Ambrose is going to help Becca Drake solve her inexperience issues. Not only is she his friend’s sister, but Griff doesn’t do commitment–not since the day he came home from war to find his house empty and his wife gone.

But he can’t get Becca’s request–or pretty much anything else about her–out of his head. What can it hurt, anyway? If it’s awkward afterwards, they can just avoid each other. Right?

Becca Drake has turned her life around, and she’s proud of how much butt she’s kicking. The shy girl with the self-esteem problem has been shown the door, and New Becca’s in the driver’s seat. There’s just one more demon she has to exorcise. Her lack of experience is messing up her romantic life. Guys who might be okay with giving her a test drive act like they’re being auditioned for marriage when they find out exactly what she’s never done.

Griff is the perfect candidate to do the deed: He’s her friend, he’s hot as heck, and neither of them wants anything serious.
Then Becca’s job goes belly up and she takes a temporary position at the veterans’ retreat where Griff works. Now she and Griff can’t stay out of each other’s way–and their entanglement keeps getting messier–and hotter. Worst of all, it’s getting harder and harder for Becca and Griff to lie to themselves about what they really want…
