Another novel that I really recommend, which mixes fantasy with social critique and science in one very interesting way, is "Soldiers of Paradise" by Paul Park.

Another novel that I really recommend, which mixes fantasy with social critique and science in one very interesting way, is "Soldiers of Paradise" by Paul Park. Its description of a world with seasons which last for generations and a caste-bound theocratic society that blends magic and touches of the modern world has a certain stark beauty to it.
