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? 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?
