1-4) Rick Riordan: Percy Jackson and the Olympians (2-5) (paper, finished 02-01) Finished the rest of the series in about a month. It was a bit teenagery at times (and probably more predictable for me than for its intended audience), but still very good. At the time of writing this I've borrowed the first book of the spinoff series from the same student who got me these.
5) Adam Christopher: Elementary - The Ghost Line (paper, finished 02-08) A birthday gift from my dad, this was every bit as enjoyable to read as the series is to watch. Christopher clearly understands the characters well and I'll eventually check out Blood and Ink.
6) Jim C. Hines: Revisionary (ebook, finished 03-04) Finally remembered to pick up the fourth installment of this amazing series, which was published a month earlier.
7) Dajo Jago: Robins in the Night (ebook, finished 03/29) Thoroughly enjoyable retelling of the Robin Hood legend, with lots more lesbians and snails and some actual believable diversity (which was complained about in the "negative" review that led me to buy the book in the first place).
8) Nnedi Okorafor: Binti (ebook, finished 07/06) Great novella-length story about a young Himba woman's encounter with "hostile" aliens on her way to an interplanetary university.
9) Nnedi Okorafor: Who Fears Death (ebook, finished 09/20) Excellent novel by the same author. Very dark and depressing at times, as it's partly inspired by genocide in Sudan. I'm glad I read it but I think next will be something much lighter.
10-12) Ransom Riggs: Miss Peregrine's Home for Peculiar Children, Hollow City, and Library of Souls (paper, ebook, ebook, finished 10/12) Girlfriend lent me the first one to read before the movie came out, and then I bought the other two for Kindle and read them shortly thereafter.
