Think Amazons. This book is about the future earth where gender roles are reversed due to a genetic disease that only males inherit. Thus, the women are the leaders, hunters, and authority figures. Males are treasured and tightly guarded. A very interesting social construct. The storyline is also well done.
Excellent book on the end of our civilization and a new one built on the ashes of the old one.... with very few men surviving.... I would love to read a prequel and a sequel of this book. I will be watching Laurie R. King's website to see if she does write more of this world.
If you like this book... read Beekeeper's Apprentice. Excellent book. An aftermarket Sherlock Holmes series...the best series.
