It Happened on the Lake by Lisa Jackson (Author)

The huge Victorian house on Lake Twilight belongs to Harper Reed Prescott, as does the private island on which it sits. Harper wants little to do with either. Twenty years ago, Harper’s grandmother died suspiciously while in her care, on the same night that Harper’s boyfriend disappeared. His body was never found, and no charges were filed. But the rumors haven’t faded. There have been other deaths, other accidents. All revolving around Harper and her family.
