What begins as a playful satire on literary ambition and the chaos of our times expands into a dazzling, polyphonic odyssey that challenges the border between fiction and reality.

As the Ren Duka novels race outwards in widening circles of influence, we encounter Dina Tatangelo, cult novelist of the New York underworld; a Japanese manga artist whose work eerily affects his family life; a grizzled Dublin taxi driver who just might ferry his passengers between worlds; a film-star facing public disgrace; and Rob Doyle, an author enduring a psychic and ontological crisis. Cameo is at once a metaphysical architecture of the imagination, a human comedy full of unruly passions, and a self-portrait across multiple dimensions. 'Where I come from, when something is called mad it's often a good thing.
