Query: Saga influenced novel written in the early 20th century.

Although the story is based in Sweden instead of Iceland or Norway and is more "novel" oriented than the crash and burn style storylines that permeate the Sagas, it is obviously heavily influenced by Icelandic/Norse Sagas and I believe this book actually won a Nobel Prize for literature. This is close to being a five star book but the story ran out of steam in the last third or so. I still enjoyed it.
