A stand-alone novel by Judith Tarrand and Harry Turtledove.
The protagonist is Nicole Gunther-Perrin, a lawyer in modern Los Angeles. After having some things go wrong in her life, and experiencing what she believes to be overt sexism, she prays to her souvenir of the Roman gods Liber and Libera to send her to Ancient Rome.
Nicole finds out that Roman Empire wasn't the egalitarian place she had thought it was, as well as finding out that life in the 2nd century is a much rougher place than she had anticipated. Unlike many “peolpe sent back in time stories”, Nicole's few attempts an invention and spreading modern values fail miserably. This sets the book apart form other such stories.
