This is a very lengthily but never boring and always interesting book covering pretty much the entire history of the vikings, it covers all the key periods from the origins of the scandinavian countries, the myths behind their pagan beliefs, their development of seafaring boats, all the major explorations to Iceland, Greenland and Vinland, the invasion years of Anglo-Saxon England, including the decades of raids upon Gaul/Frankia (modern day France), the founding of Normandy by the Viking Rollo, the history and founding of Sweden, Norway and Denmark with all their turbulent royal histories, ultimately leading to the year of 1066 featuring William the Bastard, Duke of Normandy, Harold Godwinson, brief King of England and Harald Hardrada, King of Norway.
It has some fantastic colour photographs in the middle of great historic archeological finds and discoveries and of recreated longships and fjord landscapes.
Anyone interested in Vikings at all should read this book because you do learn a whole lot more that you might imagine. It is highly recommended.
