'A nail-biting chiller, which will leave readers begging for more. Be prepared for some sleepless nights.' Michael Grant, author of Gone. Milton Lake is a seemingly ordinary town, where tales of hauntings and strange goings on ripple beneath the surface. When a mysterious boy comes to town and moves into a large, derelict house, all alone, his arrival changes everything. Shrouded in secrecy, he senses a kindred spirit in Emma Rhodes, and reveals to her a shocking truth. Someone in Milton Lake is using the fabled Ghost Machine to call the spirits of the dead back to our world. Now it is up to these two lost souls to find out who is operating the strange invention before it is too late . . . For call by call, the dead will be unleashed.
