Classic Detective Story Setup: A body is found in a locked dressing room. No one was seen entering or leaving. How did it happen? For people like Madison Gardner, the answer is very simple. They came through the mirrors. Reflection-hopping is as easy as riding a unicycle. And ten times as dangerous, with all the nefarious uses for it. That danger is upped another notch as a monster starts pacing the hallways behind the mirrors, feasting on all who wander it. Except the people don't think it's a monster. They think it's just another power-hungry reflection-hopper like all the rest. Now they want to ban reflection-hopping as a whole, and only Madison is left to unmask the real monster, backed up by a conspiratorial detective, a vengeful girl, and a rookie fireman, before time runs out.
