Maggie and the Wish Fish — E.D. Baker

With each day, Maggie is finding it harder and harder to get along with her step-mother and step-siblings while her father is away. It doesn't help that every time Maggie finishes cleaning laundry, flying pigs swoop in to muddy everything up and get her into trouble! One day while she's out collecting berries and her step-brother is fishing, Maggie happens to catch a magical fish herself! The fish promises to make one of her wishes come true, but only if she frees him. Maggie wants a new family more than anything, but how much faith can she put into a talking fish?
