Emison Sullith has to rescue her mom from the shadow world.
Twelve-year-old Emison Sullith prefers reason over impulse, but when her mom turns into a shadow and vanishes through a hole in their apartment wall, Emison finds out that there's more to life than her well-ordered reality. She is soon joined by a shadow person named Mrs. Gonzales who was sent by her mom to protect Sylvia from the Chromatics – an evil gang of color scientists in search of a secret formula that changes shadow people into their full-color version.
Problem is, Emison's mom stole the formula and left it with Emison before she disappeared. Once the Chromatics discover that Emison has the formula, they go after her. When her friend Missy is kidnapped by mistake, Emison and Missy's brother Adam decide to go into the shadow world to rescue her.
