About The Book

A romantic comedy of manners about a lavish wedding weekend gone very, very wrong with the slow-burn romance of Emily Henry and the fizzy humor of Sophie Kinsella.

The Bride: Beautiful, seemingly carefree Marigold is tired of being treated like a shallow it-girl. That’s one of the many reasons she’s excited to marry Jonathan—the handsome, kind, respectable doctor of her dreams. So when a shocking secret from her past threatens to ruin her wedding, she’ll do anything to make it disappear...even if it means tracking down a man she vowed to avoid forever.

The Maid of Honor: As the bride’s best friend, all Natalie wants is for this wedding to go off without a hitch. There’s only one problem: Natalie has secretly been in love with the groom since college. When Marigold disappears, Natalie is forced to ask whether she can keep burying her feelings for the sake of friendship...or if she’s ready to risk everything to pursue her own happy ending.

The Sister: Olivia has spent her life cleaning up Marigold’s messes. So she’s determined to keep the wedding on track for the sake of their mother, who’s battling cancer and longs for one last perfect weekend. But when Jonathan’s best man—a prickly academic with a heart of gold—ropes her into a fake dating scheme, sparks unexpectedly fly. Will Olivia sacrifice her own happiness again, or could this fake relationship turn into the truest choice she’s ever made?

Heartwarming, hilarious, and sparklingly romantic, Save the Date will have you cheering for love in all its messy, unexpected glory.
