In the future, in a place called Satellite City, fourteen-year-old Cosmo Hill enters the world, unwanted by his parents. He’s sent to the Clarissa Frayne Institute for Parentally Challenged. There, the boys are put to work by the state, testing highly dangerous products. Cosmo realizes that if he doesn’t run away, he will die at the so-called orphanage. When his chance finally comes, Cosmo escapes with the help of the Supernaturalists, a motley crew of kids who all have the same special abilities as Cosmo -- they can see supernatural Parasites, creatures that feed on the life force of humans. The Supernaturalists patrol the city, hunting the Parasites in hopes of saving what is left of humanity in Satellite City. Or so they think. Soon they find themselves caught in a web far more complicated than they’d ever imagined.
