|| Shannon and her two friends, Marge and Traci, look forward to spending the summer as employees of Arapahoe State Park, but their joy is soon spoiled by a tragic accident. Marge's cruel rejection of nerdy Del Evans results in a fight, and Del falls from the boat into the deep, choppy waters of Lake Arapahoe. His body is never recovered. The following summer, the three friends return to the park. On the anniversary of Del's death, they are shocked to find words scrawled in red across the boathouse, Die, Die, Die-one word for each girl. Did Del somehow survive the accident? Shannon senses that disaster lies ahead for all of them. And even her innocence may not keep her from being a victim of vengeance.
