This book reminded me a LOT of Octavia E. Butler. This is maybe an inevitable comparison for any black woman writer of speculative fiction, but there really is a kinship between this book and Butler's work, especially Wild Seed--in the relationships people have with science, with gender, and especially with power.
It's not a happy book. It wasn't always easy for me to read--there's a lot of violence, from rape committed by law enforcement figures to amputations performed by the protagonist. But there isn't much gore, and like Butler, Solomon explores the worst humans do to each other in order to find a way to a world where we can do better.
