I picked this up in Copenhagen Airport, thinking I'd have a good laugh while learning something as well, and being inspired.
I was wrong. I think the authors actually do try to be funny, but they are not. It becomes artificial and superficial. The result is not even mildly entertaining, just plain indifferent.
Few of the stories in the book are interesting or educating, let alone useful. And as you work your painful way through the book, they increasingly give the impression that the authors really had to come of with something. SOMEthing. To fill out 50 `chapters'. Another typical disease of this type of books: Why dos it have to be 50? Or 33? Or even 10? If you only have 7 or 8 things to actually tell, then only tell those, and tell them well. Or, in this case even better: Don't write a book!! Please.
What's more, it is not about Vikings. Not even about Scandinavia. Almost only about Swedes. No surprise, as one author's name sounds Swedish -- but t(he)y could at the very least have had the decency of taking the trouble to do a proper research. A couple of examples: Denmark has 4 million inhabitants? -- no it doesn't, it has more than 5.5 million, or a mere 37.5% more than stated in the book. And not only one Skype's founders is Scandinavian, they both are -- a Dane and a Swede. Need I say that only the Swedish guy is mentioned in the book?
Why two stars then? Well, because I'm generous. The short chapters and the easy (though not always correct) wording makes for an easy read. A loo read.
But certainly not more.
