As the seventh born of the seventh born, Ari Greimshaw has a gift of second sight. She didn't ask for this gift, which she assumed at birth, and she doesn't want it either. She especially doesn't want it when Colin Bucket dies, because Ari is certain that her gift and her misuse of it has sent Colin to his death. Ari also fears that in a moment of jealousy she has also committed her best friend, Lulah, to a similar fate of potential harm. In attempting to accept responsibility for what she believes are the result of her actions, Ari inadvertently triggers circumstances which reveal a dangerous love triangle with Lulah at its base. This is a mystery that is set around Ari's efforts to come to terms with her place in the death of a boy. It is also a superbly told coming-of-age story that follows a young woman as she deals with the confusion, misunderstanding and regret that can often accompany one on the journey from childhood to adulthood.
