A missing girl, a secret diary and unsettling revelations . . . Today is the first of September, the first day of spring, and it's been sixty-four days since I last saw Sophie Abercrombie. It's been sixty-four days since anyone saw Sophie Abercrombie. The prettiest Sophie. The missing Sophie. As Sophie MacKenzie - Mac - confides to her diary, she last saw Sophie Abercrombie kissing James Bacon, their English teacher. Mac has passed this on to the police, but there is plenty she knows about James Bacon that she has kept to herself. She hasn't even told Twiggy, the third Sophie in their once tightknit threesome. The Trio of Sophies is no more.
