Superior death, a

Park ranger Anna Pigeon returns, in a mystery that unfolds in and around Lake Superior, in whose chilling depths sunken treasure comes with a deadly price. In her latest mystery, Nevada Barr sends Ranger Pigeon to a new post amid the cold, deserted, and isolated beauty of Isle Royale National Park, a remote island off the coast of Michigan known for fantastic deep-water dives of wrecked sailing vessels. Leaving behind memories of the Texas high desert and the environmental scam she helped uncover, Anna is adjusting to the cool damp of Lake Superior and the spirits and lore of the northern Midwest. But when a routine application for a diving permit reveals a grisly underwater murder, Anna finds herself 260 feet below the forbidding surface of the lake, searching for the connection between a drowned man and an age-old cargo ship. Written with a naturalist's feel for the wilderness and a keen understanding of characters who thrive in extreme conditions, A Superior Death is a passionate, atmospheric page-turner.
