Laura Ingalls Wilder's 1937 "Little House" novel, in which the family moves into a sod house in the fields of Minnesota after being forced to leave Indian Territory. Laura and Mary finally live close enough to town to go to school and meet snobby, mean Nellie Oleson, who gets her comeuppance when she's lured into a leech-filled creek. The family finally gets a house built and a farm started when a plague of grasshoppers eats everything they've planted, leaving them penniless.
