When Monotech sets its sights on The Yard, the only things preventing the Zinger estate from being turned into a golf course are a sacred, but centuries forgotten, pact and a man who hears voices. Can Katlyn, her eccentric cousin Mitchel, and the certifiably schizophrenic Silas find six secretive, supernatural Guardian spirits in time to evict a crazed, toxic monster from their land?
