My Supernatural Life

When Mary Winchester became a victim of a horrible demon house fire, John Winchester believed he had lost the love of his life. With his two young boys, John fell into the supernatural world and dominated the top of the hunter list, raising his boys to follow in his footsteps.

What no one knows though, is that John faltered from the path of grieving and heartbroken father. When Sam turned four, John fathered two young twin girls with a woman he had only met a few times. Whenever John disappeared, leaving Dean to look after his younger brother for days, even weeks, he was with his little girls.

Nearly 22 years later, John Winchester has gone missing. Sam and Dean have gone out to look for him. What they don't know is that they'll find more than just their father.

They'll find the half sisters they never knew they had.
