Heather Worth thinks she's moving to Colorado for a prestigious art scholarship, but her true motive is Chase Russet, the enigmatic boy from her childhood who has haunted her memories for a decade. When she finds him, the reunion is nothing like she imagined. Chase is a prisoner, constantly surrounded by the same watchful "Neighbors" who isolated him years ago. As Heather digs deeper, she uncovers a terrifying truth: she's not just a curious girl stumbling into a secret; she's a pawn in a clandestine war between two shadowy corporations, and Chase is a living weapon with a rapidly approaching expiration date. Caught in a web of spies, advanced technology, and reality-bending secrets, Heather must unravel the mystery of the Neighbors before they unleash their 'final demonstration' on an unsuspecting world.
