This book hit just the right note with me at just the right time. It was one of those rare books that made me want to drop everything I was doing just so I could read - in fact, I finished this book in my car after work because I couldn't wait until I got home to read the last ten pages. So yeah, it was that kind of a read for me. That said I can see this book not being to everyone's liking. It has the same sort of grim and violent outlook you find in something like the Walking Dead, which will put a lot of people off. This is not a feel good story. There is a lot of graphic sexual violence depicted, so know that going in.
At its core I read this as a book about gender roles and sexuality. With the world's population drastically reduced, women a rarity, and pregnancy a dangerous and fruitless prospect, how does that effect the way we behave? How does this free people, sometimes in very dark ways, and how does it bind them? With a cultural breakdown, and women so vastly outnumbered, humans become sexually "liberated" in the way other mammals are liberated - with no social constructs this changes the dynamic. Some men use this as an excuse to rape and hold women as property. Some women use this as a way to collect harems, trading sex for protection. Some people feel free to choose their partners as they see fit without the societal judgement they might have previously experienced. Some people hide their gender in order to walk through the world unhindered. It's an interesting meditation on how the human animal might adjust gender roles, sexuality, and morality if society, balance, and pregnancy are removed from the equation.
In addition to having some interesting themes to chew on I quite liked the character and world building. All the characters felt distinct from one another, and their voices felt unique. The representation of bisexuality was some of the best I've ever read, and I really appreciated that as well. The world felt both real and terrifying, the feeling of constant threat looming in every encounter. This book scared me in the same way as White Horse by Alex Adams, or Children of Men. At the same time it had some hope and beauty sprinkled in (sparingly), to offset the horror of the world. For me it was meditative, haunting, frightening, and a little empowering.
If you're looking for a great read about the end of the world with a feminist bent this is a rare jewel. If grim futures, violence, or sexual trauma put you off of a read don't pick this one up. For me the food for thought far outweighed any of the ugliness.
