On the face of it, Freya lives a gilded existence, dancing solely to her own tune. She has all the trappings of wealth and privilege, a responsible job as a surgeon specialising in skin grafts, a beautiful flat in a sought-after development, and a flash car. But it wasn't always like this. Hers is a life founded on darkness. Did what happened to Freya as a child one fateful summer influence the adult she would become - or was she always destined to be that person? Was she born with cruelty in her heart or did something force it into being? In Fire, John Boyne takes the reader on a chilling, uncomfortable but utterly compelling psychological journey to the epicentre of the human condition, asking the age-old question: nurture - or nature?
