For fans of Patricia Highsmith, Julie Myerson and Ian McEwan's Enduring Love Sex Education sold 7,000 in paperback A brilliantly controlled study of paranoia

Stella lives with her cat in a top floor flat, where she waits for her clients to arrive for their massages, and her life is as perfectly ordered as the phials in her treatment room. As strictly inventoried are the contents of her rucksack, always ready by the door in case she needs to make a quick getaway. But she never goes out; she can't. When Ivan moved in he was told: no stories from the past, no unnecessary anecdotes, no questions. But can Stella keep her own rules? Yellow is the colour of gas, of fear, of jealousy. And Stella has smelt something in the air that she cannot control. Janni Visman's second novel is a twisted love story that takes place in a few bare rooms, a superbly taut thriller that confirms the arrival of a fantastic new talent.
