The story of the two green children who came out of the wolf pit and lived for a time among the villagers has survived in English folklore for centuries, and there have been several versions of it for children. This one is workmanlike and interesting, but somehow lacks the unearthliness of the original legend. It's matter-of-fact where one wants magic, and down-to-earth where one looks for mystery. However, it reads easily and does tell its tale in an effectively straightforward manner.
