Salt Lake City is hotter than hell. The Church of the Latter-day Saints is about to celebrate Pioneer Day, in honor of the Saints who crossed half a continent searching for a home. And in the sun-scorched streets, PI Moroni Traveler, fallen Saint and former football star, is searching for a vicious serial killer. The murderer's calling card is a videotape of his beautiful victims—beautiful before the self-styled "Jack the Ripper" vents his savage, woman-hating rage. The next target is Claire Bennion, the ex-girlfriend Traveler can't manage to forget. The Church wants the killer stopped, no questions asked. But Traveler has his own reasons for facing down a weird mountain cult, Zion's powerful elite, and a murderer bent on paying for his own sins in innocent blood.
