The Prince Valiant books have proved that they have a real function as bridging books from the comics to the more conventional type of historical and period adventure. Into these books has gone a great deal of sound research. Now comes a different type of book from the creator of Prince Valiant -- a book that reads some what like notebook jottings of factual content for a story about the Middle Ages. The story itself is static, lacking in any pace or build up to climax. But the text traces the year-round pattern of life in a medieval castle, the wars of those days waged between neighboring overlords, the activities of castle life, for all, the steps in training boys to advance towards knighthood. It answers a great many of the questions raised by such books as Men of Iron and of the Silver and as to the hows and whys. And the pen drawings by Harold Foster are authentic and accurate in detail. Content material rather than fiction- and it would better have been presented as such.
