When Kate meets Max in the first week of university, a life-changing friendship begins. Over the next four years, the two become inseparable. But loving Max means knowing his family: the wealthy Rippons, all generosity, social ease and quiet repression.

Theirs is not Kate's world, and yet she finds herself drawn quickly into their gilded lives, and the secrets that lie beneath. Until one summer evening at the Rippons' home, just after graduation, her life is shattered in a bedroom while a party goes on downstairs.
