Anna Pigeon / 

Park ranger Anna Pigeon is enjoying the open spaces of Colorado when she receives an urgent call. A young woman has been injured while exploring a cave in New Mexico's Carlsbad Cavern Park. Before she can be pulled to safety, she sends for her friend Anna. Only one problem: a crushing fear of confined spaces has kept Anna out in the open her whole life.

Anna Pigeon takes a job as a park ranger looking for peace in the wilderness-but finds murder instead.

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.
