The Price of Freedom

After Farrah Winchester found her father and uncle, she also discovered her true nature: lycan, the rarest of all supernatural creatures, one who is part demon, part angel, and part human. This works out well, until she gets stuck in purgatory for a year.
Now she's out, but for a price. And that price is a lot bigger than what she expected to pay.

Sequel to My Father, Sam Winchester.
