Boys will love this book. Bear Grylls knows what it takes to survive, but he is not the first.
There was American bombardier Louis Zamperini, who was stranded at sea for 47 days and only lived by catching and killing hungry sharks and drinking the warm blood of albatrosses, only to be later captured by the Japanese and subjected to life in a POW camp.
Marcus Luttrell, a navy seal who single-handedly took on the Taliban regiment before dragging his bleeding, bullet-ridden body for days through the harsh mountains of Afghanistan.
And Nando Parrado, one of the survivors of a horrific air-crash high in the ice-bound Andes, who only lived because he ate his fellow companions.
Its gruesome, but tells real tales of brave men.
