In the Detroit housing project, neighbors and schoolchildren mock Gertie's young daughter Cassie for talking to her imaginary playmate, Callie Lou. Gertie, wanting her to fit in, forbids the game, so Cassie slips off to play with Callie Lou alone in the nearby railroad yard, where a train kills her. The effort to make the child conform to the new place removes her from her mother's sight and costs her life.
Gertie has saved enough money to buy the Tipton place, a farm that would give her family land and self-sufficiency. Her mother invokes scripture and a wife's duty, and Gertie gives up the farm to follow her husband Clovis to Detroit. The novel shows that a capable person's independence can be dismantled without force, by a moral code she herself accepts, which turns her surrender into a virtue.
In the Kentucky hills, want is visible and a household can partly feed itself from its own labor and land. In Detroit, the family lives on factory wages and installment payments for goods like the new refrigerator, so strikes and layoffs threaten everything at once. Looking at the household this way shows that industrial prosperity can raise consumption while making the family more exposed and less in control of its survival.
Throughout the novel Gertie carves a large block of cherry wood into a figure whose face she never settles, uncertain whether it should be Christ or Judas. At the end, needing money, she splits the block into pieces to make mass-market dolls, saying the face could have been anyone's, one of the many faces around her. Her single great work is sacrificed to piecework, and the lost art is recast as a common humanity she has found among the city poor.
