In 1930 Abby Nichols is an eight-year-old girl growing up in Maine, but as the Depression deepens, and her mother dies, the responsibility of taking care of her family falls to her, and she has to put her dreams of going to college and becoming a writer on hold.

On the last night of summer, Emma and her Maine game warden father rescue a small domestic rabbit stuck in a fence; the very next day Emma starts fifth grade after years of being home schooled, excited and apprehensive about making new friends, but she is paired with Jack, a hyperactive boy, who does not seem to fit in with anyone--except that they share a love of animals, which draws them together, because of the rabbit.
