As the global crisis develops in the Twenty-First Century, a group of special "demon" researchers are sent from a parallel universe to embody themselves as humans and study the situation. However, in the midst of the operation, Wye-Wye, the youngest member of their team, is lost.
As she and her comrades do everything demonly possible to find him, Melusine, the team lead, is forced to do the unthinkable-employ the assistance of a "visie" (demon slang for human)-freelance journalist Paige Ballantyne.
Paige, however, gives Melusine much more to consider than just the mystery at hand as she becomes intrigued by the benefits of a "visie" life.
Together, the team must race the clock to find and bring back Wye-Wye before he can no longer regenerate. In an all-out cross-continent search, the team turns up much more than they bargained for in this urban fantasy mystery adventure.
