Katherine Singer is the daughter of Bobby Singer. She's always had Dean and Sam Winchester, growing up with them and training. Sam's just her little brother but Dean has always been more, even when she didn't want to admit it. Instead she shoved it down and locked them away. But what happens when they start to resurface stronger than ever, will he want her back? And what happens when a secret is discovered, a secret that will destroy all they've built. Who will stay and who will leave.....
