With an abandoned degree behind her and a thirtieth birthday approaching, amateur writer Bonnie Falls moves out of her parents’ home into a nearby flat. Her landlady, Sylvia Slythe, takes an interest in Bonnie, encouraging her to finish one of her stories, in which a young woman moves to the seaside, where she comes under strange influences. As summer approaches, Sylvia suggests to Bonnie that, as neither of them has anyone else to go on holiday with, they should go away together — to the seaside, perhaps.The new novel from the author of the Man Booker-shortlisted The Lighthouse is a tense and moreish confection of semiotics, suggestibility and creative writing with real psychological depth and, in Bonnie Falls and Sylvia Slythe, two unforgettable characters.
