'Kannon Dupree, US Time Marshal, travels into the past to find a present-day serial killer ... this may be her most dangerous mission yet. A fabulous new TimeStalker novel. A missing diary holding dark secrets, a lost Spanish royal treasure and a serial killer operating in the Wild Wild West... Kannon Dupree, the time travelling detective, is hired to go to New Mexico in 1867 to find the missing diary of a Wild West hero. Disguised as a bounty hunter, the chase takes Kannon from gunfights in Old Santa Fe, across hostile territory in the middle of an Indian War, via a mysterious convent of nuns banished to die in the desert and into an ancient pueblo city on a cursed mesa sacred to Coyote, the trickster god. But what she doesn't know is that the diary holds a spine-chilling secret that someone in the present may be willing to do anything to hide...'
