The Glutton by A. K. Blakemore

The 18th century is drawing to a close, and unrest grips France. Tarare has been born into a life of slender means, but when a sudden act of violence ignites in him a ferocious appetite, his extraordinary abilities to eat make him a marvel throughout the land. Travelling to Paris and beyond, through the heart of the Revolution, he journeys into a world of upheaval and depravity, in which the hunger of one peasant is matched only by the insatiable demands of the people of France.
