Gavin's third book focuses on the King penguins on the Falkland Islands. He introduces Rex, who seeks out a mate, raises a chick, and faces grave danger in the ocean! Will Rex survive? Gavin had a wonderful mentor on this book, Kathryn Wozniak, the lead aquarist and Penguin keeper at the Pittsburgh Zoo. Gavin visited with Katy and the King Penguins at the zoo as the project began. At the time, the zoo had three King penguins. A few days after his visit, all the King Penguins were sent to Texas to breed. The zoo helps in the conversation efforts of these penguins. Profits from the sale of this book benefit the Pittsburgh Zoo and PPG Aquarium. This book is a project of the Baden Academy Research Lab and Grow a Generation.
