This is the second book in Nevada Barr's Anna Pigeon series. If you haven't read any of this series, then give them a try, especially if you like mysteries or reading about the outdoors. Every book is set in a different national park, with a single exception: Deep South and Hunting Season both take place on the Natchez Trace. The first book in the series is Track of the Cat, which was awarded both the Anthony Award for Best First Novel by The Crime Writers Association and the Agatha Award for Best First Novel. Here's the long synopsis. 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 this 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. I found the following on Nevada Barr's website and thought it was interesting. "Isle Royale National Park was my first duty station as a seasonal law enforcement ranger and Anna Pigeon's second park. A number of things went into the inspiration for this book. While I was there fires broke out in the West (as they do every summer, a pity for the nearby residents but a financial boon for wildland firefighters). By sheer coincidence every man at the Windigo end of the island was sent off to fight them. Remaining was me, as Acting District Ranger, and three female interpreters. A visitor remained with us for several days after the exodus. Each day this man looked more harried and glum. On day three he came into the ranger station. He looked as if he'd lost weight and was not sleeping well. After a few minutes of muttering he asked in a tiny scared voice: "What have you done with all the MEN?" That and a wonderful old short story called, I think, something like "A Bottle of Relish" became the touchstones for the book." Nevada
