Trinity Pierce has been plagued by bad dreams ever since she can remember, and now they are seeping into reality. Her mother is ill and the family is forced to move from the yellow fields of Amarillo to the frigid winters of Pittsburgh. It is here where she begins her new life at a foreboding school - Turnbull Prep. The building is a fortress of tall ceilings, winding staircases, and unusual wooden carvings - each with their own tale to tell. Trinity makes friends quickly, but her mother's illness influences every corner of her life, often leaving her isolated. Used to being alone for so long, Trinity reluctantly turns to her newfound friends for support and meets one boy, Gabriel, who takes an immediate interest in her. As she makes her way through her new school, Trinity notices that the odd wooden carvings on the walls begin to call out to her, to move, to whisper horrible stories no one else seems to hear. But wood can't move, so were the walls driven by some machine...some computer program? Trinity is determined to find out. With her friend, Ravie, at her side, Trinity is determined to get to the bottom of the carvings and their terrible tales, but is it all in her head? She believes she may be going crazy until she meets Kane, who can also see the walls move. Together, Trinity, Ravie, and Kane lead an expedition into the innermost rooms of the malevolent school and find a twisted tale of parallel worlds, good and evil, as well as creatures who have been searching for Trinity and her gift for thousands of years. Now, they have found her and are coming to take what they want. Will Trinity trust her new friends and this beautiful boy named Gabriel, or will she succumb to the darkness and destruction that are coming for her? What part does Gabriel play in all this? Is he the savior she needs so badly, or is he just another part of her never-ending nightmare?
