At the end of John Boyne’s novel Earth, Evan Keogh, a conscience-stricken young footballer, hands evidence of his connivance in a rape to the police. Two years earlier, he and his teammate Robbie had been found innocent of the charge by a jury, whose foreperson was Dr Freya Petrus.

Freya, a consultant in a hospital burns unit, becomes the protagonist of Fire, the third of Boyne’s Elements quartet.
