This is a nice interlude kind of story in the greater universe of Mercy stories. Mercy’s half brother shows up at her house an absolute mess – he can’t speak, and barely seems to know where he is. After some investigation, they find out it’s due to some very particular not actually Fae magic.
This sends them to Montana in the middle of a storm that is so much worse than it should be. And we end up with a really interesting mash up of Norse and Native American myths and legends.
I really enjoy how the author weaves together different mythologies – she finds really good ways to make them compliment each other. And I really enjoy how she writes those characters. This is fun story. It solves an issue that was created in earlier books, so that’s advancing the plot, but it’s otherwise mainly a fun side adventure.
