Lost in the Wild is a MN. published book and it came out about two yrs. ago I think. Its written by Carey Griffith, and the story is actually 2 different stories. The first story takes place in the BWCAW about a man who becomes lost. The second story is somewhat the same but a man becomes lost in the Canadian park the Q.  One is with a group of boyscouts I think and the other story is a man who steps away from his camp to just look around and he looses his way. Both are gripping reads.
