She is a rising tennis star, and he is the coach who trained her. He wakes in a hospital bed with a concussion and a missing year, and she is at his side wearing a wedding ring, calling herself his wife. She knows his favourite drink, his old matches, every soft spot he has. Forty-five chapters of an island anniversary where no guests arrive, a rival with a very different account, and a reckoning over what really put him in that bed.
