In rural Texas in 1901, thirteen-year-old Callie nurses a butterfly with a broken wing and delivers a baby lamb, despite her mother's disapproval of Callie's "unladylike behavior."
Out in their boat exploring the San Marcos River, Callie and Granddaddy see all kinds of nature fish, mockingbirds, ammonites, and more. But when Callie spots an owl in the water, she knows it's in trouble. With quick thinking and quick action, she and Granddaddy bring the bird aboard but will they be able to save its life?
When the Tate family dog, Ajax, has a run-in with a porcupine, things get prickly--and dangerous--quickly. It'll take Callie's quick thinking and doctoring, along with a little help from Dr. Pritzker, to make things right. Will Ajax learn to leave other critters alone?
