Two friends. One pact. The performance of their lives.Hannah Abbott is stuck in a dead-end relationship and at a job she loves but that barely pays the bills. The four walls of her tiny New York City apartment have never seemed so small. She’s barely toasted her thirtieth birthday when her old college friend Will knocks on her door with an unexpected proposal. Will Thorne never forgot the marriage pact he made with Hannah, but he also never imagined he’d be the one to initiate it. One ex-fiancee and an almost-career-ending mistake later, however, he finds himself outside Hannah’s door, on bended knee, to collect on their graduation-night pinky promise.With both of their futures at stake, Hannah and Will take a leap of faith. Now, all they have to do is convince their friends and family that they’re madly in love. As long as they follow the list of rules they’ve drafted, everything should go smoothly. Except Will has never been good with rules, and Hannah can’t stop overthinking the sleeping arrangements. Turning thirty has never been so promising.
