This has to be one of the best historical novels on any subject ever written - a totally engaging, nay enthralling, saga of viking adventure at the turn of the previous millennium. It brings 10th century northern Europe vividly before the reader; it has a very appealing young hero, Orm Tostesson, whose story we follow eagerly and avidly from inexperienced youth to adventurous old age as he participates in viking expeditions as far apart as England, moorish Spain, and the long road to Miklagard. It's very much a smell-the-salt-sea-spray, feel the swaying deck, almost trip on the slippery blood sort of book, but it's additionally fascinating to anyone who's ever wondered how the Vikings could possibly relate to modern-day Danes and Swedes (this book will tell you). It's full of fascinating stories about such famous folk as King Harald Blue Tooth and the Jomsvikings, relating for example how a young warrior's long blond hair saved his life. And it's extremely funny, particularly on the subject of attempts to convert the less amenable Northmen to Christianity. And it's also in places moving; and in other places, an edge of the seat suspense thriller. I first found it in a 2nd hand bookstore in Stockholm in 1989; the copy I bought then has been re-read so many times that it has now fallen to pieces and I must have another, and several spares to give my friends.
