Nomi and Zee are Local Borns—their father a convict condemned by the British to the Andaman Islands, their mother shipped off with him. The islands are an inhospitable place, despite their surreal beauty. In this unreliable world, the children have their friend Aye, the pet hen Priya and the distracted love of their parents to shore them up from one day to the next. Meanwhile, within the walls of the prison, Prisoner 218 D wages a war on her jailers with only her body and her memory.
