This book is amazing. It takes a lot of suspension of reality to get through because the first part assumes that time-travel is scientifically possible. However, that doesn't last long and if you can get through it (I'm not a big sci-fi person, so it was hard for me) the actual historical part is amazing. It not only focuses greatly on the role of women in the colonial time period, but it also focuses on the hypocrisy on colonization and the power that women still had despite their disadvantage of sex. Also interesting is the fear that the white colonizers had of their whitge women being lured away by the "black" native and tainting her.
