Unbroken | S.W

Killing Lilith was supposed to break the final seal - not release her. Dragged from the Cage alongside Lucifer, Katherine arrives with secrets the Winchesters can't afford to ignore and powers they don't fully understand. Dean knows better than to trust her, especially when nobody can explain whose side she's really on. But Sam can't seem to stay away from her. Drawn in despite every warning, he becomes increasingly obsessed with the mysterious girl tied to the Apocalypse, even as the line between ally and threat begins to disappear.
