The sign over the covered antique mirror said DO NOT TOUCH. Twelve-year-old Nora wished she had listened.

Mirrors reflect what is in front of them, but what happens behind the glass—to the reflections themselves? Nora finds out when her own reflection, aka Fake Nora, changes places with her one night. Nora is shoved in a place that looks exactly like her house with no echoes, dull lights, and muted sounds. It isn't her home at all, simply a shell of a place she loves.

Fake Nora is living her best life in Nora's house, feeding on the fear of her little brother while no one else at the house knows anything is wrong.

Inside "reflectionland," Nora meets thirteen-year-old Jesse, who has been stuck in his mirror since the forties, and he warns her that they aren't alone in the house. There are others sneaking around, known as the bad ones—spirits of people who gave up after vanishing in the mirror.

Refusing to stay a reflection forever, Nora conjures a plan to escape, but Fake Nora isn't about to give up her life in Nora's home. And Jesse? He could become a bad one forever.
