Mallory Michaels has three rules she lives by:
Never drink a mimosa that’s less than ninety percent champagne.
Always have a plan—and a backup plan for the backup plan.
And never repeat your biggest mistake.

Her biggest mistake? A one night stand with Shane Evans, the most infuriating man she knows. It meant nothing. Just one reckless night she’d rather forget. That should’ve been the end of it. But when their mutual best friends put them on a job together, a powerful client offers Mallory the opportunity of a lifetime. But Shane slips up, putting them in a situation where they now have to pretend to be a couple in order for her to get this job. Seems simple enough, but not they’re stuck together for a week on a luxury yacht. Shared spaces. Forced smiles. Pretending they’re in love.

Mallory and Shane have always been on the same page about only one thing—neither of them does relationships. Casual is safer. Cleaner. There’s just one problem, though. The longer they play the part, the more real it starts to feel, and the harder it becomes to pretend that one night between them was just a mistake.
