"Lost in the Wild" by Cary Griffith...
This book, in an odd way, holds a special place in my heart. The setting is key... as the "wild" is, more or less, the area of the north woods near my parents home in Northern Minnesota. I read it while we were up north over the summer, so it was kind of spooky to look out into the woods and realize that the area you are in isn't that different than the area that put the lives of the lost people in danger.
The essence of the story tells the tale of two people, who get lost on separate trips in the Boundary Waters Canoe Area Wilderness area / Canada's Quiteco wilderness area. They both thought they were able to survive in the wild, and both were in serious danger.
The story highlights the strength of individuals who face huge obstacles and have to rely on themselves in very challenging circumstances. It is also about the strength and persistence of the rescue workers who took extraordinary measures in order to find them.
If you want a book about a wilderness area like no other, read this book.
