The world of Paper is pure white until someone adds lines of black, sharing their soul to create a soul creature.
After losing her mother to a new form of lung cancer, Casey is filled with grief and anger. Seeking out the help of a Summoner, and a group of kids who also have a reason to fight, she prepares to destroy the tobacco companies. First though she must learn to Summon soul creatures from the world of Paper. But with demons hiding in plain sight all around them, the fight may be over much too quickly.
With her family torn apart, Casey has nothing left but her hatred. Yet this burning hatred threatens to consume her, and keeps her soul creatures from reaching their full potential. To make matters worse, the tobacco companies have their own, tainted, versions of soul creatures.
Facing these odds, Casey must let go of her hatred, or the demons will devour them all.
