Two other favorites from last year. The Island of Dr. Moreau by H. G. Wells but you should follow it immediately with The Daughter of Dr. Moreau by S. Moreno-Garcia. It's sort of a companion piece written by a female, indigenous author. It bookends the sci-fi by a white guy nicely.

Also, I'll always tell people they should check out the book that is credited with starting sci-fi as a genre. Frankenstein; or, The Modern Prometheus by Mary Shelly. It's horror, it's sci-fi, it's speculative, it's fucking awesome.

And the Blue Ant trilogy by Wiliam Gibson. He's deff not for everyone. He can be really hard to get, and he just dumps you into his world and starts. There is no tutorial. But if he clicks for you, you'll love it.
