Recs for Hugo novel reading?

As the year comes to a close, the thoughts of the Hugo nominator turn to planning her reading for the next four months. Obviously, I cannot read every single novel that was published in 2016, not even every novel that reviewed well and/or seems likely to be a contender, even if I wanted to. The end-of-year lists are already coming out, and I'll be applying to those, as well as the always-helpful Hugo eligibility spreadsheet, but there's almost too many options there.

So I figure, why not start by asking my friends and followers, whose opinions I trust? What's your must-read book from 2016? (I'll get started on short fiction and other categories later; new series are probably more than I'm willing to tackle right now.) I'm already planning to read All the Birds in the Sky and Ninefox Gambit; books published in 2016 that I've read are here. Some possible nominee contenders there, but only one slam-dunk, so your thoughts are definitely welcome.

FFXV

Once upon a time, I was very excited for this game. Then my trust in Squeenix began eroding, until this happened, and I washed my hands of it.

Which means that I completely forgot that a new game in what used to be my favorite series is coming out today, until I saw a poster for it on my way home from work.

How things change.
