The character from The Curious World of Calpurnia Tate helps animals big and small in this second book in a chapter book series by a Newbery Honor author.

When Callie and Granddaddy go exploring by the river, Callie discovers a leaf covered with spots. Those spots, it turns out, are eggs, and those eggs become butterflies. One of her newly hatched butterflies has a problem, though—its wing is broken. Can Callie find a way to help this butterfly fly?

Mother's prize sheep, Snow White, is pregnant and about to give birth. With Dr. Pritzker off helping a colicky horse, it falls to Callie to deliver the lamb. Callie takes the situation in hand, bringing the lamb into the world—and getting her fair due from Mother!
