Poppy Porter's ex is getting married ... to her ex best friend. To land her dream job of partner in the most prestigious firm on the Upper East Side, Poppy must now pull double shifts as their wedding planner and maid of honor. And the icing on a truly craptastic cake? Leo Nass. Handsome, infuriating, womanizer, and ... the best man. Despite their longstanding loathing, Poppy doesn't see Leo coming. Literally.

One ruined cake.

One archnemesis.

One hour to save the wedding.

Can they put their hatred aside long enough to save Poppy's job and Bridezilla's head from exploding?

Piece of cake, right?
