I like this book. So far it is my favorite Octavia Butler book. I like that the ending was not taken for granted, that the lines of good and bad weren't so clearly drawn that you felt you didn't have to actually read the book. The book contains horrors and violence and stares them in the face clearly. The book has great commentary on religion, slavery, and gender. It is told from a creative narrative structure that shows the writings of different characters. It allows a layered story to develop over time.
I especially have encouraged Detroit activists to read this book. The post-apocalyptic world encourages responses of community/ cooperation and authoritarianism/dependence. Both responses are portrayed in the book. I think this book has great relevance in the post-commons privatized world that we may be entering in.
