Hylas has come to Tykanos to build an aqueduct. He has not come to enjoy the island's main attraction: the six houses where the companions of Tykanos, courtesans both female and male, offer tea and elegant conversation. Yet he cannot ignore them as he finds himself renting a room in one of the tea houses and meeting his neighbour, the beautiful, chronically ill companion Zo.

Over breakfasts in Zo's garden, the two men begin a friendship that transforms the isolation of their lives. But Hylas's aqueduct project is threatened by bureaucratic delays, and Zo is pressured to secure a rich patron to help support his failing house. When they have begun to hope that they have found a home in each other, the world seems intent on forcing them apart.
