In a dystopian world dubbed The Society, when teenagers reach the age of 16, they have a choice. They can remain human, give birth to children and get a job. Or they can choose to be transformed into an animal, whatever animal fits their personality best. But if you are transformed into a dangerous animal, then you are carted off, never to be seen again. Calista Rose Garcia is faced with her choice, and as she balances perfectly on the fulcrum of death and prosperity, she comes to realize that some personalities are not what they seem.
