Don't know about year of release, but these are sci-fi books I enjoyed reading this year...
The book of strange new things (Michel Faber). This isn't typical sci-fi, it's hard to describe. It's quite slow paced. I can't really talk about it without spoiling it. I really felt impacted by it though, I think the book has a deeper philosophy that isn't really mentioned but requires thinking about the meaning. I thoroughly recommended it if you are willing to be thoughtful about a book and not just after laser and space battles. Another book by the same author (under the skin) is also good, and has been turned into a very weird film with Scarlet Johansson.
Other good more conventional sci-fi stuff...
Extracted series (R.R. Haywood) Not alone (Craig a. Falconer) Themys files series (sylvain neuvel) We are legion series (Dennis E. Taylor)
