She's my roommate and my best friend's forbidden little sister. And now she wants me to teach her how to date.

Me. The himbo who's messed with half the women in the city. The guy whose nuts her brother will feed to the squirrels if he finds out.

I should've said no. But it's Mia-my Mia. She's tired of being a wallflower, and I'm the perfect guy to give her advice.

I shouldn't teach her how to kiss. We shouldn't practice in my bed.

I shouldn't know how many freckles she has on her stomach, or love the way she fits in my arms.

But what definitely shouldn't happen? The dude she's known her whole life-the one who was just supposed to help-should not want to spend the rest of his life doing it.

Mia's brother might break my face, but Mia? She might break my heart.

The PS 2 staff room shenanigans continue in Teach Me a Lesson-a super spicy romantic comedy that features a brother's best friend who's a childhood-friend-to-lover, roommate, coworker, and reformed rake all in one. You'll laugh, cry, and swoon with Mia and Elias's forced proximity, their secret relationship, and enough spice to set your heart (and e-reader) on fire.
