Supernatural

Kassandra "Kasey" Marie Winchester has spent her entire life in the shadow of monsters and the men who hunt them. The youngest child of John Winchester, she was raised on the road beside her older brothers, Sam and Dean, after her own mother's sudden and unexplained death. Gifted with the ability to see spirits and feel the emotions others try to hide, Kasey has always been both an asset and a quiet liability to the family.

Now eighteen, she rides shotgun in the Impala as the brothers take on their first cases without their father. She knows the weight of the life they lead. She knows the cost of the secrets they keep. And she knows that some things-once seen-can never be unseen.

As the Winchesters begin hunting the creature that has haunted their family for decades, Kasey must decide how much of herself she is willing to risk... and how far she will go to protect the only family she has left.

Some bloodlines are cursed.
Some gifts are a warning.
And some sisters were never meant to survive the dark.
