Just outside of the city's neon Strip, in the bleak wastelands of Nevada's desert, Las Vegas Metro police discover the mauled corpse of a young and beautiful showgirl. Called to the crime scene is Detective Sergeant Romulus Poe -- a thirty-five-year-old Vegas native and a seasoned, fifteen-year police veteran. A loner with a love of justice, Poe immerses himself in the horrific case.
The corpse is badly mutilated. Poe is particularly struck by its dreaded similarities to a horrifying slaying done by an anonymous monster dubbed "the Bogeyman". Immediately, Poe forms an investigatory team; the handsome detective Stephen Jensen; Patricia Deluca, a homicide newcomer; and forensic pathologist Rukmani Kalil, who is also Poe's part-time, unorthodox girlfriend.
From the start, the team is mired in a web of intrigue, and the urgency of resolution becomes frenzied when another young nighttime desert dump is found a month later. From Native American mysticism and medieval folk legends to untold modern scientific secrets, Poe must sift through Vegas' sordid history and dark underbelly to solve a series of gruesome murders -- and save a beautiful woman he had once loved -- before all of them are caught in a deadly dance of Moon Music.
