Well, I seem to have failed at the 50 Books Project. I couldn't think to say anything about Nova by Samuel Delany. It's a great book, filled with some good characters and a detailed space opera setting. But what can I add to it that other people haven't already said. Here is a review by someone who wasn't bowled over by it. (I feel differently. I've read it three times and could read it hundreds more.)
I just finished Jack Faust by Michael Swanwick. It was excellent. It retold the Faust tragedy with Mephistopheles played by an alien intelligence who wants nothing more than to wipe out humanity. To do that, they give Faust all the knowledge he seeks and he changes his world.
I've always been fascinated by the Faust tale. I read Christopher Marlowe's version when I was in college. It was shortly followed by a translation of Goethe's version. I've also enjoyed Randy Newman's Faust. (I disagree with that review by the way. I think the humor, especially in the conversations between God and the Devil, is great.)
Swanwick really takes on modern technology and its effect on society and what unlimited knowledge could really mean. It's good stuff. I'm surprised the book hasn't gotten more attention. I'm so glad I picked the book up for $2 from a "Buck a Book" store a couple of years ago. Best $2 ever spent.
So, while I may have more to say about the books I read, consider me a failure at the 50 Books Project.
