Grave DangerPaperback - 1997
Cassie thinks she has the answer when one day she sees a portrait of Catherine Denning, an ancestor who looked just like her. Is Cassie being haunted by Catherine's ghost? She discovers that other girls in the family have died shortly after turning sixteen . . . and realizes that the ghost drove them to their deaths.
Cassie is running out of time -- unless she can lay Catherine to rest, the ghost will claim her life as well as the life of her younger sister. Can Cassie overcome this awesome power from beyond the grave, or is history destined to tragically repeat itself?
