Lois McMaster Bujold at her very best! This novella is the newest in the World of Five Gods series, and a direct sequel to a previous novella - Penric's Demon. The story is something of a theological mystery, which is very different than it's predecessor. It's a good story all by itself, and since it is a novella, a pretty quick read. For me, it was hard to put down once I started to read it.
Now, I will not say it that there is any book or story that must be read before this one. Certainly, if you've read Penric's Demon, or any (or all) of the novels set in this world, your experience will be different than if this is your first experience with the World of Five Gods. But Bujold always tells you enough in each book or novella for you to enjoy it by itself. So if this story appeals to you, go ahead and enjoy!
I gave this novella fife out of five stars on Goodreads and Amazon.
I will be considering this for a Hugo nomination in 2017
