This was a great fantasy read and worthy of the Hugo award. The story takes place in what appears to be a very distant future earth where geologically the earth is always threatening to bring a catastrophic event that would lead to widespread death and destruction (a "fifth season"). There are multiple characters with fantastical powers and the world building is very well done. The story follows three different female characters at different places and times (it was just a bit confusing to follow at times), but there is a big reveal in the later parts of the book that I for one did not see coming.
I think the story ends perhaps a bit too abruptly, but with two more books in this trilogy, I can't wait to read the next.
