Bee thinks she has everything: a successful business repurposing wedding dresses, and friends who love and support her. She's given up on finding love, but that's fine. There's always Tinder. Nick thinks he has nothing: his writing career has stalled after early promise and his marriage is on the rocks, but that's fine. There's always gin. So when one of Nick's emails, a viciously funny screed intended for a non-paying client, accidentally pings into Bee's inbox, they decide to keep the conversation going. After all, they never have to meet.
But the more they get to know each other, the more Bee and Nick realize they want to. They both notice strange pop culture or political references that crop up in their correspondence, but nothing odd enough to stop Bee and Nick for falling hard for each other. But when their efforts to meet in real life fail spectacularly, Bee and Nick discover that they're actually living in near-identical but parallel worlds. With a universe between them, Bee and Nick will discover how far they'll go to beat impossible odds.
