River Kings: A New History of the Vikings from Scandanavia to the Silk Road by Cat Jarman

3.0

I learned stuff, that's for sure but there was something about the writing style of the author that just didn't quite work for me.
It's more of a 3.5, but I'm rounding down because I just didn't quite enjoy it, despite the fact that it was very interesting.
