Abby was left at the altar four years ago. So, when she runs into her ex-the one who ghosted her on their wedding day-she does what any totally well-adjusted adult would do: grabs the first warm body next to her and kisses him. Unfortunately, that warm body belongs to her cold-hearted work nemesis, Jonathan-the same man who was strutting over to insult her vodka cran and make a snide comment about how she allegedly fumbled her marketing presentation that morning. (She didn't. They both know she didn't.)

The kiss was staged, on Abby's part. Jonathan, naturally, was shocked... though he can't exactly say he hated it. But the pretend romance that follows catches them both off guard. The very next day, her ex is introduced as the new owner of their company-and now Abby and Jonathan are stuck faking a passionate relationship at a work corporate retreat, complete with a shared cabin, nosy coworkers and six years of petty sabotage that's one HR complaint away from disaster.

Of course, nothing about this plan screams "HR-friendly." But between forced proximity, a suspicious ex and one very complicated fake relationship, they both start to wonder what's real and what's just another performance.
