Thanks to her superstitious mother, Esther knows some tricks for avoiding bad luck: toss salt over your left shoulder, never button your shirt crooked, and avoid black cats. But even luck can't keep her family safe from the Great Depression. When Pa loses his job, Esther's family leaves their comfy Chicago life behind for a farm in Wisconsin. Living on a farm comes with lots of hard work, but that means there are plenty of opportunities for Esther to show her mother how helpful she can be. She loves all of the farm animals (except the mean geese) and even better makes a fast friend in lively Bethany. But then Ma sees a sign that Esther just knows is wrong. If believing a superstition makes you miserable, how can that be good luck?
