Regency College senior Julian Brehm's uneventful student life is derailed when he falls for Nina Rinaldi, a beautiful young revolutionary engaged in political activism against the authoritarian regime that rules the country and wages a deceitful, distracting war. Julian's love for - and moral alliance to - Nina eventually leads him into a vast undercity beneath the metropolis. Then, east by train and into the war zone itself, where mortal danger in that expanding cemetery of millions threatens Julian's life; what he witnesses will alter how he perceives the Republic and ultimately his fate within it.

Julian's adventure can be seen as our own, a world of vacillating morality and unceasing violence. Apathy and passion. Fear and courage of purpose. Julian's is a hero's journey into the dark unknown. A love story, which extends in many directions. A war novel of incredible scope and horror. A suspenseful mystery novel with a moral puzzle at its core. And a coming-of-age tale of a young man seeing the world he was born into, more dangerous and more beautiful than he could have ever imagined. Metropolis is a meditation on the meaning of virtue and goodness in the face of the most monstrous crimes. It could just as easily be the story of us.
