This is the last of my read-in-2016 books to post!
Ursula Vernon (under her penname T. Kingfisher) released this story as an online serial over the last several months, and it ended on December 29. It was wonderful following it as a serial, with new updates to look forward to twice a week! And when I read the last part it was weird to think that was actually over.
It's a portal fantasy, and stars a girl named Summer who gets sent to the magical world of Orcus by Baba Yaga in search of her heart's desire. She meets friends, but she also meets awful things happening. The whole thing is done with Vernon's usual depth and soul, as well as her usual delightful quirkiness, and the combination of these things makes for a wonderful book. In the early stages of release, Vernon seemed to be somewhat nervous about presenting this book to the world, thinking it maybe too odd to really work for people, but: it works. It really works. It's wonderful.
It's hard to know how to talk about this book in more detail though, because I was reading it for months, so a lot of the details were already fuzzy by the time I got to the end. But I highly recommend it, and you can read the whole thing here
