Right away, Opal knows she can tell Winn-Dixie anything — like the fact that lately she’s been thinking a lot about her mother, who left when Opal was three. And that her father, the preacher, won’t talk about her mother at all. And that she’s lonely. But with such an unusually friendly dog at her side, Opal soon find rself making more than a few unusual friends.
