In the leafy, charming town of Chapelwick, the Bittersweet family has been a fixture on High Street for as long as anyone can remember. Their rambling black-and-white building houses all three generations of ghost-sensitive Bittersweet women and their business, Blithe Spirits.

On her twenty-seventh birthday, Melody Bittersweet converts the disused back storeroom into her office and opens her own business. Unlike the rest of her family, she’s not taking down messages from ghosts—she’s taking them out. 

Soon, the Girls’ Ghostbusting Agency takes on its first case: a grand old house that won’t sell because a trio of incumbent ghost brothers raise merry hell whenever prospective owners arrive to view it.

It soon becomes clear that there’s a whole heap of unfinished business between the Scarborough brothers—including murder—and Melody isn’t the only one trying to unravel the mystery. Leo Dark, her rakish ex and business rival, is also on the case, along with the TV crew that trails him.

To make matters worse, the sarcastic and skeptical (and annoyingly good-looking) local reporter Fletcher Gunn has his nose in the story as well. Sniffing out a way to publicly discredit the Bittersweets is his favorite assignment—and has absolutely nothing to do with his inability to resist Melody.

With her business on the line, it’s up to Melody to work out the brothers' issues, but can she protect her own very susceptible heart from Fletcher’s charm? Does she even want to?
