Katie Wilkinson has found the perfect man at last - but one day he disappears from her life, leaving behind only a diary for her to read.
The diary was written by a new mother, as a keepsake for her baby son. In it she touchingly recounts the initial romance between herself and the child’s father, and the unparalleled joy that motherhood has brought her. As Katie reads this moving account, it becomes clear that the lover who has left her is the same man as the husband and father in the diary. She reads on, filled with terror and hope as she struggles to understand what has happened - and whether her new love has a prayer of surviving.
