The Water Cure by Sophie Mackintosh

The world is a bad place where you must be strong to survive, fear strangers and only trust your family - this is what sisters Grace, Lia and Sky have been told their whole life. There is only danger, disease, and death outside the family island compound so they must never let anyone (especially men) in and never leave. When their dad goes away on a supply trip and doesn't return the girls and their mother are even more vigilant in their efforts to be pure and away from the toxic world outside. The arrival of two stranded men and a boy will turn their secluded world upside down. This dystopic, survivalist world where one man attempts to have total control over his family and the strict secluded way the girls are brought up echoes the themes in HANDMAID'S TALE and VOX. These three young women are starved for affection and love but taught to fear men - it is not difficult to see how at odds this will make them and the possibilities for disaster are endless. This will be a great choice for book clubs - the discussion material is as endless as the sea that makes up their world.
