When her mother is killed in a riding accident, nine-year-old Amy is mute and traumatised. She cannot remember what happened, and she is haunted by a nightmare she cannot fully explain. She becomes obsessed with her father, clinging for dear life to their relationship.
Six years later, the chance discovery of a postcard gives her the clue she needs to uncover the truth about her past. It takes her to Italy, to a man she has never met. Was he her mother's lover - or her killer?
The threads of the past lead inexorably back to the present and, as they gradually allow her to remember those horrific moments she thought forever buried, finally - and in more ways than one - Amy comes of age.
