What makes an eagle, an eagle? Or a bear, a bear? Todd's dad, a famous scientist specializing in the study of animals, has cracked the code and discovered the essence that makes every animal unique. Now he is able to create a serum that gives those unique qualities-and abilities-to anyone who ingests it. But before his discovery can be introduced to the world, several of the vials are stolen. Soon after, a sudden rash of bank robberies featuring large and terrifying animals rocks the community. Todd and his dad know who is doing it. How they're doing it. And why. The only question that remains is: How are they going to stop them?
