All Persephone Kipp wants is a chance to interview for a job at the area's leading graphic design company, but her life takes a drastic detour when she begins seeing people with ghostly animal ears growing from their heads...people who later turn up brutally murdered. Piper Holleworth doesn't know she has invisible, ethereal ears sitting atop her head...not until she meets Seph and finds herself stalked to the ends of the earth by monstrous, shadowy entities. Now these two strangers must work together to survive as they race westward in search of an ancient artifact said to be the only thing capable of stopping the relentless wraiths. But the terrifying path before them will test their courage to the very limits.
