Lydia Sorensen, a young woman, could have everything if it wasn't for the social disorder that has kept her caged her entire life. She has been living and working on the family farm, near a small township in Western Australia in her own self-imposed isolation, until she once again sees one of them. But Patrick Marsden isn't one of them, he's not a figment of Lydia's unusual mind, he's from somewhere else - somewhere real. The fact that he's not even physically present, that he has sent his fourth dimensional form through a doorway from his world, has him shocked that she is aware of him at all. Threatened by a clandestine organisation, avoiding detection from invisible enemies and with the very fabric of Earth's reality on the line, Lydia is forced to the realisation that she has no choice but to work together with this mysterious entity. Throughout the course of their adventure, relationships will be tested, beliefs will be challenged and treachery will be revealed, as our heroes do battle to save Earth.
