Starlight Cove's prim little librarian has despised me since the first day I parked my motorcycle on her sidewalk. Now our feud has landed us as roommates…and she just asked me to teach her every dirty thing she's never experienced.

Making Penelope Shea lose her mind has been my favorite hobby since she moved here. But our infamous daily sparring backfires when the town's meddling grandma sentences us to five hundred hours of community service…or thirty days of living together.

Penelope chooses cohabitation with the enemy to protect her spotless record. I agree because watching her unravel sounds like fun.

What I don't expect is to discover my rule-enforcing roommate has secrets—namely, a hidden career penning filthy romances and a list of sinful lessons she's written about but never learned firsthand.

Like an idiot, I volunteer as her tutor.

Penelope calls it research. I call it trouble. Because somewhere between her first lesson and her first tattoo, she goes from being in my head to being in my bed.

Now she's under my skin as permanently as my ink is under hers.

Our month is almost up. But I've never been good with rules—and letting her walk away isn't one I plan to follow.
