LONGLISTED FOR THE MAN BOOKER PRIZE 2018
Grace, Lia and Sky live in an abandoned hotel, on a sun-bleached island, beside a poisoned sea. Their parents raised them there to keep them safe, to make them good. The world beyond the water is contaminated and men are the contamination. But one day three strangers wash ashore - men who stare at the sisters hungrily, helplessly. Men who bring trouble.
