I picked this book because it was free on my iPhone. I was surprised at the content. It wasn't what I expected from a book called The Viking. The plot was good, the characters were believable. I'm not an expert on Viking times, but it seemed to do very well from a historical standpoint. I loved that it was clean. The only problem I had was with the dialogue. The author uses the dialect of the people when they speak, which is good, but after a while it gets rather tiring to read.
All in all, The Viking is a good, clean historical book.
