Top five of 2015? Eek, that is so hard! Nimona has to be one of them (monster giiiiiirls!), and then, I read this really great history of the DRC by David van Reybrouck, and Anne Jamison's Fic was an excellent introduction to fandom studies, and Claire North's Touch kept me up late, and then probably Between the World and Me.

(That is more nonfiction than I was expecting!)
