Household Gods is a science fiction/time-travel novel written by Harry Turtledove and Judith Tarr.

The story is of a young 20th century woman who is dissatisfied with her hectic life of balancing her career as a lawyer with being a mother and dealing with her deadbeat ex-husband and sexist coworkers. Believing the past was a better time, she makes a wish one evening after a particularly wild day before a plaque of two Roman gods, Liber and Liberia. She then finds herself waking up in the body of one of her ancient ancestors in a 2nd century ancient Roman city in what is now Austria. In general, she finds out the hard way that life back then was not quite what she thought it would be: no womens' rights, no effective medicine or clean medical practices, slavery taken for granted, and no tampons.
