This is the conclusion to the tale of Alfadas, which started in "Elven Winter", though it is not a conclusion of the events that started in that book. Those are referenced in the first book, "Elven", though it's a while since I read that so I don't recall how much detail was included. 

This is a faster-paced tale which centres more around the interactions between the Humans and the Trolls, as they continue their war against the Elves, and spans events both in Albenmark and the Fjordlands of the Humans. 

The world-building, battles, characters and emotional impact of this story is a step up from "Elven Winter", which was wonderfully rich in its detail, and is subsequently even more engaging. 

This is a satisfying conclusion to the trilogy, though it does lend itself to the possibility of further stories, which I would definitely read.
