After a gunshot leaves her paralyzed, Barbara Gordon enters the Arkham Center for Independence, where Gotham’s teens undergo physical and mental rehabilitation. Now using a wheelchair, Barbara must adapt to a new normal, but she cannot shake the feeling that something is dangerously amiss. Within these walls, strange sounds escape at night; patients go missing; and Barbara begins to put together pieces of what she believes to be a larger puzzle.

But is this suspicion simply a result of her trauma? Fellow patients try to connect with Barbara, but she pushes them away, and she’d rather spend time with ghost stories than participate in her daily exercises. Even Barbara’s own judgment is in question.
