Fleeing dark forces and unfounded accusations across Europe in the years between World Wars, a young man named Vango has been in danger for as long as he can remember. He has spent his life running along rooftops, fleeing to isolated islands, and evading capture across Russia, Paris, New York, and Italy. In the shadow of a rapidly changing world, can Vango find those who have hunted him for so long and uncover his true identity?
