For readers who can swallow the notion that a 12-year-old newly orphaned girl from a wealthy, sheltered upbringing would run away to become a hobo, this is a gratifying adventure from DeFelice (The Ghost of Fossil Glen, 1998, etc.). A year after the Great Crash, Frankie’s widower father has lost everything and commits suicide. The girl is to go to live with her aunt in Chicago, but Frankie cashes in the train ticket, disguises herself as a boy, and hops a freight to freedom. Luckily, she meets a boy who knows the ropes; Stewpot, as he’s called, with a cough to foreshadow his eventual demise, has been riding the rails for a long time. Frankie soon realizes how hard life is, for they are always cold, hungry, or both; train-hopping is dangerous and illegal. They persevere until Stewpot becomes too ill to travel; with the little money she has, Frankie attempts to get medical help, but no doctor will go out of his way for a hobo. When Stewpot dies, Frankie understands that her real life is with her aunt in Chicago. DeFelice gets the details of the period right, with especially well-realized scenes of what it means to be a hobo, even though much of this is just one more girl-disguised-as-a-boy story. Those seeking out tales on unfamiliar aspects of the Depression—or a different kind of survival story—will find it engaging. (Fiction. 8-12)
