Ten-year-old Lucy Griggs's mother has just died, leaving Lucy orphaned and living on the streets of 1866 New York City. Then Lucy hears about the Children's Aid Society, a group that sends orphans out West to new homes. Lucy knows she'll never replace her mum, but maybe now she'll find a family--and even a little sister--to love.
But the family that takes her in is far from ideal. Mr. Snapes seems kind, but Mrs. Snapes is a bitter, angry woman. And Emma isn't the sister Lucy has dreamed of. Emma is a girl who people call "simple." Can Lucy learn to love this less-than-perfect family?
