Now this is a cool SF novel! Adrian Tschaikovky's Children of Time completely blew my mind. Here's the description from Wikipedia:
All true. This is a fantastic book and the portrait of the uplifted spider society is amazing; so vivid you could see it existing in real life (somewhere). And it's now available in a Kindle edition for $0.99; if that isn't a bargain I don't know what is! Grab it immediately if not sooner.The book's plot involves a planet inhabited by evolved spiders uplifted by human scientists, and their later discovery by the last humans alive in the universe. The work plays off the contrast between the societal development of the spiders and the barbaric descent of the starship crew of the last humans.The work was praised by the Financial Times for "tackling big themes—gods, messiahs, artificial intelligence, alienness—with brio."It was selected from a shortlist of six works and a total pool of 113 books to be awarded the Arthur C. Clarke Award for best science fiction of the year in August 2016. The director of the award program said that the novel has a "universal scale and sense of wonder reminiscent of Clarke himself."
