"The beast is out of the cage. And she thirsts for vengeance."
In the world of Mirrordom, secrets lurk like shadows. For every child that's born is entirely Good, unable to kill, steal or lie. But immediately after it appears a Mirror twin, capable of only bad things.
Fable, a Mirror girl with a twisted past, dares the impossible-to find her Good twin. Along the way, she meets Cobalt, a mind-reader with secrets of his own. As alliances shift and betrayal beckons, can Fable protect Cobalt from someone who wants to kill him? Or will the darkness consume them both?
