We all have personas: different sides we show in public, at work, to our friends or family, one we only see when alone, and perhaps a side we deny. Most of us do not even recognize those personas. Through an inexplicable link to minds with memories spanning history, Seth Warren has developed six unique personas, collectively known as the Shadows. As Seth tries to convince himself that these memories are figments of his imagination, an assassination attempt awakens his Shadows and throws him into the reality of Earth's best-kept secrets, the Immortals Among Us. One Immortal breaks the rules to eliminate Seth, prompting others to do the same to protect him. While his new guardians prepare him for his greatest challenges, trouble brews inwardly. As they help Seth through these trials, the Shadows become increasingly self-aware, and direct contact with their idols, the Immortals, only encourages their growth. How much longer will they be content with the back seat of Seth's mind?
