While vacationing in Egypt. . . Jeannette Walker, a cynical scientist jaded by swarms of tour groups and knick-knack shacks, is lured by a teenage tour guide to visit a newly discovered tomb. No other tourists there! Inside the chamber, she tumbles down a shaft and 3000 years back in time. Now, in a world where deities walk the streets and prophecy heats up the air, Jeannette is desperate for normal and the simple pleasures of sanitation and refrigeration. However, a slave master hawking a cat-headed girl derails her homebound mission, and Jeannette—penniless in this ancient world—steals the girl, bringing down the tireless fury of the slaver. Saddled with a newly awakened mummy and the cat-headed girl, Jeannette contrives a plan to free them from the slaver's ire, but will she have to dive into the belly of the beast to succeed?
