Six deaths mar the holiday mood as summer vacationers enjoy Wisconsin's beautiful Door County peninsula. Murders, or bizarre accidents? Newly hired park ranger Dave Cubiak, a former Chicago homicide detective, assumes the worst but refuses to get involved. Grief-stricken and guilt-ridden over the loss of his wife and daughter, he's had enough of death. Forced to confront the past, the morose Cubiak moves beyond his own heartache and starts investigating, even as a popular festival draws more people into possible danger. In a desperate search for clues, Cubiak uncovers a tangled web of greed, betrayal, bitter rivalries, and lost love beneath the peninsula's travel-brochure veneer. Befriended by several locals but unsure whom to trust or to suspect of murder, the one-time cop tracks a clever killer.
