Rational and pragmatic, Amy Steadford has no belief or interest in the supernatural - until strange and disturbing dreams begin to threaten her previously held notions of normalcy. After a chance meeting with a mystic who gives her a powerful and ancient amulet, Amy embarks on a search for answers to her new questions about what lies just beyond the temporal world. Amy discovers that she has been called to join the ranks of a secret and sacred group that protects the uninitiated from the universe's dark forces. Responding to the call, however, involves dangers beyond Amy's wildest expectations. Her very survival depends on her ability to navigate the dimension that lies beyond the cusp of the universe, and ultimately, to cross the Great Divide.
