Children of Time, by Adrian Tchaikovsky

This was a lot of fun. It reminded me of A Deepness in the Sky because of the humans and the spider, and of The Crucible of Time because of the biological-based technology that the spiders developed.

I'm not sure if I liked the ending or not. Maybe I'm just upset that I didn't see it coming, and part of me wonders whether Tchaikovsky didn't leave enough clues or if I'm just dense. It's probably the latter.

This may be the best book I've read all year.
