When 10-year-old Bud Caldwell runs away from his new foster home, he realizes he has nowhere to go but to search for the father he has never known: a legendary jazz musician advertised on some old posters his deceased mother had kept. A friendly stranger picks him up on the road in the middle of the night and deposits him in Grand Rapids, MI, with Herman E. Calloway and his jazz band, but the man Bud was convinced was his father turns out to be old, cold, and cantankerous. Luckily, the band members are more welcoming; they take him in, put him to work, and begin to teach him to play an instrument. In a Victorian ending, Bud uses the rocks he has treasured from his childhood to prove his surprising relationship with Mr. Calloway. The lively humor contrasts with the grim details of the Depression-era setting and the particular difficulties faced by African Americans at that time. Bud is a plucky, engaging protagonist.
Other characters are exaggerations: the good ones (the librarian and Pullman car porter who help him on his journey and the band members who embrace him) are totally open and supportive, while the villainous foster family finds particularly imaginative ways to torture their charge. However, readers will be so caught up in the adventure that they won't mind. Curtis has given a fresh, new look to a traditional orphan-finds-a-home story that would be a crackerjack read-aloud.
