Query: A Great Feminist Sci-Fi Novel

I came across the name Octavia Butler when searching for science fiction books written by a black woman with a black woman as the protagonist and I found thos gem! If you are into the concept of humanity destroying itself and having to give up part of itself to survive, this book is for you. This book uses metaphors to discuss complex subjects including the role of women, the role of science and genetic enginering, the contradiction that is humanity and learning how to start over when there is little trace of the past. Dawn is an easy read and will definitely cause you to read Adulthood Rites and Imago. A great book!
