This is an excellent book about a largely ignored chapter of European history. Filled with stories about the Vikings, Moors, Magyars, and the Papacy, Reston paints a facinating picture about the consolidation of christian power in Europe. Filled with facinating annecdotes, and quite a few horrifying atrocities this is one of the few historical texts I can give a universal reccomendation to. Especially reccomended to readers of Scandinavian or Hungarian descent; whose history by myth or generally ignored. The history of the Papacy has to be read to be believed; a good groundwork for understanding the crusades and the turbulent history of christianity is laid in those chapters. Ironically, the accesible nature of this book, and it's wonderful readability, may make it seem like a frivilous catalog of mutilation, but this is a well researched work and absoloutely worth reading.
