Special Agent Analiese Valentine – aka "Val" – lived and died for her career. Possessing a sixth sense for as long as she could remember, Val always knew she was different – and so did everyone else. So different, in fact, her own mother – apparently unable to tolerate her daughter's unusual gifts – abandoned her, forging internal scars so deep most relationships, if any, were cultivated at a safe distance. A near-tragic accident opens unexpected doors – some otherworldly – changing her life in ways she'd never imagined possible.

Dr. Maxwell "Max" Thornton, a psychiatrist, ironically lives an almost reclusive life except for his practice. Although his empathic abilities allow him to help his patients in ways most practitioners never could, the effort is taxing, at times debilitating. Keeping a limited and selective clientele, he manages to pursue a career and maintain his sanity, convinced normal relationships are out of the realm of his reach.

When a guarded agent and a reluctant empath cross paths, unexpected revelations occur and a delicate thread binds them to one another as a predetermined Fate begins to unfold, sending them plummeting into a war between good and evil.
