Why You Should Never Kiss A Grump — Erin Nicholas

The problem with wanting his friend's much younger sister who's too sweet and innocent for him? His grumpy asshole personality doesn't work on her. She knows him too well. And when Sara Bradford decides she wants Jason Mac Gordon too? He's screwed. In the bad way. But the good way too.   What? He's supposed to resist her? Still, this has to be temporary. He's too old. And cynical. And he likes things too dirty. And, oh yeah, her brother will never forgive him.  this book was previously published as Just My Type (Just Everyday Heroes: Day Shift/ the Bradfords)
