Caliban's War by James S.A. CoreySecond in the Expanse series, this volume revolves around the crisis on Ganymede, and the associated blue-eyed beastie. Entertaining adventure SF, recommended.
Far-Seer by Robert J. SawyerA tale of Galileo, if Galileo was a sentient dinosaur living on the moon of a tidally locked gas giant. Interesting world- and myth-building, recommended.
Winter Witch by Elaine CunninghamSet in the world of the Pathfinder roleplaying game, this is a light fantasy about a Viking woman, an urban mage, and the icy witch who brings them together. Mildly recommended.
Damnation Alley by Roger ZelaznyLoosely similar to the movie, murderer and rapist Hell Tanner is given a chance at a clean slate if he'll ferry a plague cure across a ravaged America. It's clearly supposed to be some sort of redemption tale, but Zelazny missed the memo that some crimes don't get redemption. I honestly prefer the movie.
Venus Equilateral by George O. SmithFixup novel of a series of stories published in the 1940s in Astounding, revolving around a communications relay station and the scientific geniuses therein. The science is advanced and accurate for its era, but has not dated terribly well. (The problems they encounter in communicating with, and locating, spaceships were solved in much simpler ways within the author's lifetime.) By the end, the science has advanced so far that it's almost shifted genres from hard SF to morality play. Mildly recommended.
