I have never read anything like this and hope to read more from this author in the future. When there is a war in the timeline, Tess and Beth end up being involved in the aftermath. In this book, there are two factions that travel through time and have the ability to modify the outcome of history, culture, and life. The women's group is the Daughters of Harriet after feminism pioneer Harriet Tubman. The men's group is the Comstockers. They are able to use the portals that are found to travel to different points during history to affect change. The women dedicate their lives to attempting to make edits in time that will help shape the future. In this book, the Comstockers are trying to destroy the portals. I loved the style of writing and the overall content of the book. This was one of the most creative books I have ever read.
