What happens when a husband's dying wish is for his wife to find a new love . . . before he's even gone?

Ben and Harper have had a rough start to their marriage. After a surprise late-stage cancer diagnosis, Ben comes up with one final wish for his wife: he wants Harper to find a new partner before he dies. Harper is resistant to this wacky plan. If she can't have Ben, then she doesn't want anyone. Finally, he lets it drop, but not before the New York Times sends a journalist to do a feature story about Ben's life . . . and his idea. When Harper opens the door, she is stunned to find the one man who got away. Or, the man she spent one perfect week with a decade ago and never saw again: Liam Hale.

Suddenly, Harper is faced with her ultimate what-if:

What if Harper had ended up with Liam instead of Ben?

What if she'd pursued life as an artist instead of teaching?

What if it had all turned out differently?

After making a wish, Harper wakes up to find herself in a parallel universe . . . where her what-ifs become a reality.

Is the grass really greener, or is she standing right where she should be, even as she inevitably faces the pain of losing the one she loves?
