Blindsight

One of the best scifi books I have ever read in my life. Goes straight to my top 3 ever. It is a “Rendez-vous with Rama” meets “Alien” and from there everything goes downhill (yes, going from “Alien” to something worse), but it is also a “Name of the rose” in the sense that it actually hids a ton on philosophy under the pretext of a great mystery story. Add to that plenty of original scifi ideas about how humanity might evolve (similar somewhat to Alastair Reynolds' scifi), grimness and darkness and almost military hard action, thrilling exploration, mindfucking spy twists, good focused writing, biology and physics and sociology and psichology and so on - and you get a really great and horrifying adventure, but also a cold, heavy, depressing one.
