Arnold and Hewett (Stories in Stone, 1996, etc.) record the harrowing rescue of a baby gray whale who had become separated from her mother off the coast of California. She was discovered on January 10, 1997, exhausted, hungry, and near death. J.J. was 14 feet long when she was brought to SeaWorld as a young calf. Gaining 900 pounds in the first month, she had to be moved to a new home by crane. Her caretakers started planning on giving J.J. skills so that she could be released and survive on her own in the ocean. Divers put her food on the bottom of the pool, each day in a different location, so she could practice searching. Arnold is relaxed in her telling, allowing the already dramatic events to unfold naturally: “Everyone cheered as J.J. took a big breath, dove deep, and disappeared. The young whale was on her own.” Full-color photos capture the excitement of J.J.’s release, but also the hard work of preparing her for her return to the sea. (Picture book/nonfiction. 5-9)
