Everyman

Ian Covey is a doppelganger. A mimic. A shapeshifter. He can replace anyone he wants by becoming a perfect copy; taking the victim’s face, his home, his family. His life. No longer a man, but a hungry void, Ian Covey is a monster.
David Tirado is a massive, hideous colony organism, a gestalt entity. The sum of Covey’s discarded parts. A roiling, chaotic patchwork of vast and varied personalities, memories, and physical forms that used to be a man − many men − David Tirado is a monster.
Sophie Tirado’s identity has been eroded by the tides of a long relationship, and now the man she gave herself up for has been stolen away and replaced by a mimic. Caught between the Doppelganger and the Gestalt Entity, she will try to save her husband, but there might be nothing left of him.
Virtue has a veil, vice a mask, and evil a thousand faces.
