Interesting premise. Tess is a time traveler with the purpose of changing the timeline of women's rights or stopping the people who wanted to shut down the travel machines. Her group of activist women are called the Daughters of Harriet and they are being opposed up and down the timeline by a group of men called the Comstockers. While going back in time to 1992 to locate time-travel opposers, Tess encounters her past life and events at a concert in California where a murder occurred. Should Tess intervene and change history? Refreshingly new in the genre of time travel, this book combines a socio-political construct with traveling through time with a group of like-minded individuals striving for social change.
