The Oppenheimer triplets have been reared with every advantage: wealth, education, and the determined attention of at least one of their parents. But they have been desperate to escape each other ever since they were born. Now, on the verge of their departure for college and so close to their long-coveted freedom, the triplets are forced to contend with an unexpected complication: a fourth Oppenheimer sibling has just been born. A wickedly funny and chillingly clever novel from the author of 'The Undoing'.
