Sugar Legowski-Gracia wasn't always fat, but fat is what she is now at age seventeen. Not as fat as her mama, who is so big she hasn't gotten out of bed in months. Not as heavy as her brother, Skunk, who has more meanness in him than fat, which is saying something.

Sugar's life is dictated by taking care of Mama in their run-down home - cooking, shopping, and, well, eating.
