When Devyn Lancaster comes home from a busy shift at the hospital, the last thing she expects to find is a woman weed-whacking her garden. It gets worse when she learns her ex-husband invited the woman to trade houses with him--all without telling her a thing about the plan.

Robbie Price was looking forward to a month-long vacation in San Diego. A break from the Seattle rain in exchange for doing a few home repair projects and taking a cute dog to the beach seemed well worth a house swap. Then she meets her coworker's ex-wife.

For Robbie and Devyn, even tolerating each other feels impossible at first. And neither expect to learn to like each other. But at the end of the month, parting ways is what feels impossible.
