I can vividly remember reading Sarah Moss's gripping 2009 debut, Cold Earth, and since then she has gone from strength to strength. Her previous novel Ghost Wall had the critics raving and this, her first for Picador, should generate the same excitement.Summerwater is set in a rainy Scottish campsite over the course of a single day and night at the height of summer. The inhabitants of six tatty cabins, cooped up with their families, are mostly stuck inside owing to the bad weather, with not much to do except watch the other residents. As we move around the cabins, and listen in to characters ranging from young children to teenagers, to middle-aged parents and elderly retirees, it becomes clear that there are deep divisions; by age, or class, or along political lines (this is very much a post-Brexit novel). One family-a mother and her daughter-wearing the wrong clothes, behaving the "wrong" way, do not fit in. There is a sense of unease from the beginning of the novel, that builds -almost imperceptibly-to a deafening thrum of dread, and by the time I reached the end of the novel I could hardly breathe. So, so good.
