King of the Wind
by Marguerite Henry
Newbery Medal 1949
The story of a mute Moroccan boy and his horse traveling across Europe as their fortunes go down, up, down, up again, down further, slightly up, down and out, and finally up again for a happy ending. Especially for the horse, who becomes a very popular stud.
More of an animal story than a boy story, we never get to know too much of the boy or see him grow/change, except through the fortunes of the horse. But quick pace, some humor, and the underdogs come out on top in the end.
