Leviathan Wakes (The Expanse #1) by James S. A. Corey - I enjoyed this whole series. I like that the physics of space travel is respected among the politics/mystery. Each book in the series is a bit of a different genre set in the universe.
Spinning Silver by Naomi Novak - Eastern European folk tale akin to Rumplestiltskin.
An Absolutely Remarkable Thing by Hank Green - Contemporary fiction with a scifi bent. Ultimately hopeful, it explores the consequences of viral fame.
