Octavia Butler is one of the giants in SF, but I'm a little ashamed to admit it, and a little confused as to why, but I've never read any of her novels, even though I've really enjoyed the few short stories of hers that I've read.
Well, I've finally rectified that situation. I just finished
The Parable of the Sower. Wow. Very, very good. I can see why Butler is one of the SF giants. It's a coming of age story of a girl finding hope and community in an America that's turned into a third world nightmare. That description sounds simplistic, but it is a very moving and engaging story, and well worth a read.
The dystopic view of America that she presents here is disturbing, mainly because it seems so very plausible to me. Dystopias are a staple in SF, but the ones that really hit home are the ones that seem plausible. I think that one of the things that makes SF relevant is that good SF writers take what they see around them and fast forward everything to see where that leads them. Readers can then take those extrapolations and see what they say about society and themselves. Butler's vision in this novel are kind of depressing on a wide scale, but hopeful on at least a small, personal scale.
If you haven't read any of her work, I'd highly recommend it. I know I'll be picking up more of her novels.
