An appealing though fundamentally unconvincing story of character regeneration by the author of the very fine Daughter of the Mountains Jonathan Adams, eleven years old and regarded as the town bad boy by the small Western community, is given a horse by a young married woman on the condition that he become a ""gentleman"". The condition proves to be unnecessary, for in the process of earning the horse's keep, Jonathan learns what ""steady purpose"" means, makes new friends, and also discovers that in order to discipline animals you must be disciplined yourself. There is sound horse information here for the fans, but young readers may feel that Jonathan is too emotional and prissy in reformed state and his sudden change of heart in conforming to adult standards too sudden.
