The day after her high school graduation, Caro Spencer opens a private detective agency. Only, Caro isn’t your typical PI. She devotes her life to eradicating the supernatural creatures that plague her hometown—creatures that the other citizens of Pine Grove, SC are happy to ignore. Though Caro is used to fighting demons, werewolves, and vampires, everything changes when she discovers a zombie horde. With the help of her best friend, Jeremy “Penny” Penrose, and other allies she meets along the way, Caro must find and stop the creator of the zombies before Pine Grove is destroyed.
