What happens when your world goes to hell in a handbasket? Will there be anyone to count on during your darkest days? One girl finds out when her nightmare world tries to kill her.

When Piper discovers an old antique mirror on the attic of her new home, she has no idea what terror she unlocked. Eerie shadows lurking in the night and estranged voices crying out for help are only the beginning. As Piper’s world comes crumbling down, she realizes everything that she believed was imaginary, might have been real all along. Something is very wrong with that mirror. And if she doesn’t find out what, the mirror might end up killing her. With some help of old and new friends, Piper tries to get to the bottom of the mystery. One thing is for certain: the mirror preys on the guilty. But what exactly is she guilty of?

When Alison was stuck in Mirrorland, all she wanted was to be alive again. Now she’s gotten her revenge by inhabiting Piper's body and trapping her behind the mirror. But pretending to be Piper is more difficult than she imagined it would be. On top of that, the borders between Mirrorland and the real world are crumbling. Danger abounds, demons appear in high school, and if wasn’t for the help of a new mysterious guy, Alison might not have escaped. But there’s more to this guy than meets the eye, and she’s determined to find out what, especially since it might be related to her own supernatural problems. Meanwhile, Piper tries to convince the Horseman of Death to help her return to her own world, but he's got his own hidden agenda, which may cause more serious risks. Can Piper find a way to restore the balance before both worlds collide?
