The spellbinding new novel of love and friendship from the Number One bestselling author of THE READING GROUP 'I think you can look at a woman, or talk to her, or listen to her, for five minutes or so, and you know how she'd behave in that situation, and once you have figured that out, you know pretty much what she's going to be like in any situation.' They meet at university in the heady days of the 80s: four women with little in common but an eagerness to live life to the full. And over romantic crises, long gossipy nights and too many bottles of wine, they form the Tenko club and swear they'll always be there for each other. Twenty years later, that promise is put to the test.
