To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have no complaints about this book. It is not long, but covers the range of the topic. A good introduction or a good overview.
One thing I liked in particular, and I read the Kindle version, was that it contained many links in the text. I don't know how many, but let's say 1 to 3 per page. These links typically led to Wikipedia pages, where one could read a little more on a particular subject, as well as take one on to other related topics. Say, for example, you were reading: "Because of her (the ship's) high stem and stern, she could also venture out through the surf and across vast bodies of water, such as the Baltic or the Skagerrak...." In this example, both "Baltic" and "Skagerrak" are highlighted for links. Now I knew where the Baltic was, but I didn't know about Skagerrak, so I clicked on it. Leads to a Wikipedia page, with a map at top, and all the usual Wikipedia details below. Well, it turns out I did know where that was, but not what it was called, so that was useful.
I hope to see more books linked so well in the future. Thank you, Mr. Wernick.
I enjoyed learning about the Vikings' contributions to culture and government. I'm still thinking about the contrast between their brutality and crudeness and their contribution of strong, decent centralized government to some of the areas they conquered. The book is not the deepest exploration you will find, but the loss of depth is balanced by the ease of reading. It was a quick and pleasurable read that I would recommend to anyone who would like to know more about the Vikings without having to wade through a lot of heavy writing.
