May is helping out on a neighbor's Kansas prairie homestead—just until Christmas, says Pa. She wants to contribute, but it's hard to be separated from her family by 15 long, unfamiliar miles. Then the unthinkable happens: May is abandoned. Trapped in a tiny snow-covered sod house, isolated from family and neighbors, May must prepare for the oncoming winter. While fighting to survive, May's memories of her struggles with reading at school come back to haunt her. But she's determined to find her way home again.
