Octavia E. Butler, the grande dame of science fiction, writes extraordinary, inspirational stories of ordinary people. Parable of the Sower is a hopeful tale set in a dystopian future United States of walled cities, disease, fires, and madness. Lauren Olamina is an 18-year-old woman with hyperempathy syndrome--if she sees another in pain, she feels their pain as acutely as if it were real. When her relatively safe neighborhood enclave is inevitably destroyed, along with her family and dreams for the future, Lauren grabs a backpack full of supplies and begins a journey north. Along the way, she recruits fellow refugees to her embryonic faith, Earthseed, the prime tenet of which is that "God is change." This is a great book--simple and elegant, with enough message to make you think, but not so much that you feel preached to.
