When Johanna Langley starts seeing visions of another life, she feels her world slipping away-yet nothing could prepare her for the journey that awaited her. During a vacation in the Colorado Rockies with her boyfriend, Nate, and her son, Daniel, their retreat is abruptly ended when the trio's fate collides with a group of spring break revelers that lands them in the unthinkable-a completely foreign world seemingly unconnected with the one they left behind.

In this new world where supernatural creatures and ulterior motives from those around them are the norm, Johanna and her companions must forge alliances and navigate growing tensions among themselves. As they begin to display signs of new and mysterious abilities, they face hidden forces determined to trap and entangle them in dangerous political power struggles. With only a wise, enigmatic wizard as their guide, the companions fight to uncover the way home-if only they can survive long enough to find it.
