Maplemead Castle is crawling with ghosts, and the new owners need them gone. When Melody Bittersweet and the Girls’ Ghostbusting Agency arrive on scene, they quickly identify the main troublemaker swinging from the chandeliers. A century ago, stunning trapeze artist Britannia Lovell plunged to her death in the castle's grand ballroom, and has continued to haunt it ever since. But did she really just fall, or was there something more to her demise?

Forced to work with Leo Dark, her scoundrel ex, and the infuriating, irresistible reporter Fletcher Gunn, Melody’s investigative powers are under the strain of a heart pulled in two directions. She needs her team in top form, but her best friend Marina’s cake pipeline goes AWOL, her assistant Artie’s distracted by a giant sausage roll, and the pug Lestat is scared witless by a lion. Melody has her work cut out for her.

Somewhere, hidden in the castle, is a heart-breaking secret, but what will it take to find it? And is there a chance it could set Britannia free, or is she doomed to repeat her last fateful act forever?
