I had my mind blown repeatedly by 2015's bumper crop of science fiction, but one novel stands out even so: Luna: New Moon, Ian McDonald's hybrid of Heinlein's "The Moon is a Harsh Mistress" and "The Godfather," an unlikely and spectacular success of a novel that left me drooling at the thought of a 2017 sequel, which drops today: Luna: Wolf Moon.
