Sarah Keating was sure she’d be married by 30. Husband, kids, the kick-ass career helping adults with Down Syndrome—she assumed she’d have it all, and there’d be no need to fall back on the marriage pact she made with her best pal from college.

But a tipsy message she sends from her birthday party brings Ian Nolan to her door ready to rock her world, and not just with mind-blowing sex. He’s up for tying the knot, and has a million pragmatic reasons it makes perfectly good sense.

As Sarah and Ian test drive their marriage-of-convenience, they navigate awkward business dinners, a slippery steam room hookup, and a costume party gone awry. Their friendship is stronger than ever, and the sexual chemistry is off the charts.

But is that enough to make a marriage work, or will one of them fall hard and end up brokenhearted?
