Gracie Holland can plan the perfect Happily Ever After-unless it's her own. After a soul-flattening breakup, she has rebuilt her life planning weddings at Larkwood-an ivy-covered estate where she also lives. But when her beloved boss passes away, Gracie suddenly finds herself pitted against a love-allergic divorce lawyer who is determined to sell both her place of work, and her home.

Jude Larkwood cleans up romantic disasters for a living, so he has no intention of keeping Larkwood as a wedding venue, but there's just one problem: his Nana may have left Jude the estate, but she's left the guest cottage to the maddeningly romantic wedding planner, who has somehow turned his mind into her permanent residence.

So, when Gracie proposes that he help her plan her ex's shotgun wedding to prove Larkwood is worth saving, he agrees, but if she fails to convince him by the big day, she'll sell him her cottage. As bickering and cake tastings turn into late-night confessions, Gracie and Jude find themselves breaking every vow not to fall for each other...
