Crack your head, knock you dead, then Prince Harming's hunger's fed.
It's 1977, and Kenny Maxwell is dreading the move away from his friends. But then, behind the walls of his family's new falling-apart Victorian home, he finds something incredible--a mummified baby and a note: "Help me make it not happen, Kenny. Help me stop him."
Shortly afterwards, a beautiful girl named Luka shows up. She introduces Kenny to the backward glass, a mirror that allows them to travel through time. Meeting other "mirror kids" in the past and future is exciting, but there's also danger. The urban legend of Prince Harming, who kidnaps and kills children, is true--and he's hunting them. When Kenny gets stranded in the past, he must find the courage to answer a call for help, change the fate of a baby--and confront his own destiny.
