Peter Watt’s Blindsight is a great novel. It has scary, scary aliens (don’t read it in the dark), some pretty great action scenes, and some really cool sci-fi.
I found myself pausing at one or two points to look up particular phrases or ideas, but for the most part Watts manages to weave in explanations without being too obvious or clunky, but still not making it too hard for the reader. The action’s fast, and he tells a good story.
Some of his ideas on consciousness I don’t agree with entirely, but he told a good story about them, and it was just a really fun read. [For reasons why you might think consciousness is adapted, I’d recommend starting somewhere near here, but that’s a whole other post].
