Everybody lives there lives knowing there birthday. They know the time, the day, the month, and the year they were born, but we live our lives every year passing the day we will die, and never knowing it. Well except in Cassidy's world it's different.
When a person becomes 5 years or less from the time they will die, small numbers appear on there wrist. The numbers represent there death date. They are called "Experation Dates." Nobody in history has ever been able to change there date, but maybe it's time for a change.
Cassidy hasn't recieved her Experation Date yet, but when she does, who knows what will happen?
