Charlie's beloved grandfather is ill, and Charlie will do anything to save him. He brings home Blue Sky, a lively baby raven, because his Native American friends claim the intelligent birds have powerful medicine. Grandfather, a naturalist, is intrigued, and urges Charlie to keep a nature journal about Blue Sky. But caring for--and protecting--a wild creature is a huge responsibility. Charlie's observations teach him wondrous things about ravens--and some surprising lessons about humans, weaving natural history, myth, and a family narrative about life and death.
