Query: I've lost count of how many times I've read this book

From the beginning you are caught up in the viking age, and the story of Shef, who changes the course of history through the help he recives from the Norse Gods in the form of visions. As an ametuer historian, I found this novel exceptional, and as someone who personally followes the old norse gods, I was not dissapointed. The Gods and Goddesses are portraied truly, I get the feeling the author has had experience with them himself, or at least the input of someone else who does.This is a long book by itself, full of action. The two books which follow it only get better.
