The Family Business

Francis and Jane are two completely different teenagers, but they have one thing in common.

They are both Winchesters.

The only people who know they exist are their mother and John Winchester. Sam and Dean have no idea. Francis and Jane are twin sisters and the offspring of Dean. Under the training of John himself, Francis and Jane are taught to hunt. But despite John's efforts to let them be normal children, they are thrust back into the life of hunting when Azazel captures them and tortures them for information on Dean, whom they know nothing about.

When they finally get away, they don't have much left except each other. Follow them as they try to find out who their parents are and figure out how to stop all the monsters that plague the country.
