Set in a vibrant American city, this paranormal cozy mystery blends FBI crime scenes, heavenly hijinks, and spectral sleuthing in a race that stretches from the mortal world to the gates of Heaven. Death was not supposed to derail their fun. Mabel and Millie have been causing havoc together for decades, and they are not about to let a little thing like death stop them. Bored with Heaven’s endless perfection, these two lifelong troublemakers hatch a plan to sneak back to Earth for some good old-fashioned haunting. But their spectral shenanigans take an unexpected turn when they stumble straight into an FBI investigation for a vicious serial killer. Enter Sarah Sadler, a brilliant but struggling FBI agent who can see and hear them thanks to a recent near-death experience that almost wrecked her career. As the body count rises, Millie and Mabel realise that solving crimes is far more interesting than causing trouble, especially when they have unique ghostly talents to help Agent Sadler crack the case. With time running out and lives on the line, this unlikely trio must learn to work together across the boundaries of life and death to catch a murderer before they strike again. Perfect for fans of Mary Janice Davidson’s Undead series and the sharp humour of Janet Evanovich’s Stephanie Plum series, this afterlife mystery blends laugh-out-loud mischief, female friendship, and fast-paced serial killer suspense with a supernatural twist.
