Change of Heart by Kate Canterbary

Grey’s Anatomy meets a gender-swapped Wedding Crashers in this spicy rom-com about a one-night stand with The One, walking the tightrope of love and workplace ethics, and knowing which rules are worth breaking.
Every summer, superstar surgeon Whitney Aldritch crashes weddings with her best friend. The first one was an accident though after a decade of dropping in uninvited, they’re masters of their craft. They keep the rules simple and they never go to bed alone.
Then there’s Henry Hazlette, best man and the best one-night stand of Whit’s summer. She never imagined she’d see him again but now he’s one of her new surgical residents—and completely off-limits.
Whitney has staked her reputation on leading the hospital’s new ethics initiative. While Henry is under her supervision, they have to keep it professional. But it doesn’t help that she can’t turn around without running face-first into his offensively broad chest or rubbing up against him in crammed elevators. Also not helping: the way he smiles at her like he can hear her every not-safe-for-work thought.

All they have to do is survive this residency—and the accidental tarot card readings that hit too close to home, a few uninvited houseguests, and the hospital’s hyperactive rumor mill—but only if they’re prepared to bend some rules as the feelings go from just for tonight to get it out of our systems to mine.
