The Future of Another Timeline by Annalee Newitz
My rating: 3 of 5 stars

Occurs in a universe where there are six mounds of rock that when hit in the right combination allow time-travel througout earth's history. They are well known and time geologists use them all the time to not only view history but edit it. This is different from most time-travel stories where the characters are usually worried about changing history and causing unexpected results. They can't make massive instantenous changes (like killing Hitler) to history, the changes have to be slow, like planting a seed of a thought in a person's mind. In this version of the timeline the supression of women is slowly being increased, but a group of women are fighting back by editing the timeline. Learnt a bit about a few historical figures like Anthony Comstock, a special agent in the 1890's who was allowed to read every suspected liberated women's mail and arrest them for anything he deemed obsecene. The book has a parallel story going of the teenage life (in the 90's) of one of the main characters. The novel did peter out a bit at the end, but overall a good read.
