Lumen Mary Fairchild looks like she has everything going for her. Perfect family life, loving parents, and happiness to boot, but Lumen is not like other 18 year olds. She is a Hunter and she has been training her whole life to fight demons and creatures that lurk in the dark--not something a typical American teenager would be caught doing on a Saturday night. On her 18th birthday, Lumen receives a letter from John Winchester--her mother's brother-in-law and her uncle. Upon reading the letter, Lumen only becomes confused. The only thing written in the letter from John, is an address, a license plate number, and a phone number. Sam and Dean Winchester never knew about their cousin Lumen, but they are about to.
