first off excellent review. I thought that just like Prospero Burns the ending was really the best part.(although not as drawn out but i still loved that book) The final battle in my opinion had a large amount of emotion which was needed. I took the interpretation of "no wolves on Fenris" as that they are the emotional and psychological manifestations of the planet and its inhabitants. I know a little deep and off the wall but i think it fits with the mythology of the Fenrisians
