This is the story of a Norwegan underground fighter training in England, parachuting into Norway at night and then completing his mission while dodging the Germans. At age 10 this was the first book I read and I could not put it down. I felt terror on every page as our hero in this non-fiction thriller evaded the ruthless Germans in persuit of his mission. I read this book 45 years ago and have never forgotten how much it turned me on to reading. A fantastic book I am trying to find for my 11 year old son.
