Translation State, by Ann Leckie
Leckie follows her many award-winning novels with a sci-fi tale that's also a gripping mystery. Focusing on three characters from a vast cosmos, the narrative explores identity and relationships through the intersecting stories of Enae, the agender grandchild of a powerful family who inherits the task of finding a missing person--an endeavor that sends her down a rabbit hole; Reet, an orphaned loner with disturbingly inhuman thoughts and behaviors that hint at something darker; and Oven, the synthetic life-form who fights her way out of the hive that threatens to subsume her. Readers will be up late as this trio crashes together in a story spanning time, space, and genre.
