John and Liz have left the city to move to a remote house on the shores of a lake. But along with the boxes, they have brought their trouble with them. They find the new house already haunted – by their old disappointments and longing.

Though the house is barely unpacked, Liz's sister, with her children and husband, have come to visit. Over the course of a hot, slow week, tensions simmer; things go unsaid. And as outsiders descend on the house the atmosphere grows claustrophobic, the pressure near unbearable.

As summer draws to a close, and their family is thrown into crisis, John and Liz must confront what it means to belong to a place – and to each other.

'A finely drawn portrait not only of a couple in crisis, but of a world on the verge of disaster. McMullan writes with a masterful naturalism' Financial Times

'A masterclass in apprehension, exposing the fissures between an imagined life and its reality with stealthy power, and boldly upending reader expectations. Richly unsettling' Daily Mail
