Book excerpt: On October 26, 1914, Ernest Shackleton’s Endurance set sail from Buenos Aires in pursuit of the last unclaimed prize in exploration: the crossing of the Antarctic continent. The crew stood on deck to watch the city fade away. All but one. Eighteen-year-old Perce Blackborow hid below in a locker. But the thrill of stowing away with the legendary explorer would soon turn to fear. Within months, the Endurance, trapped and crushed by ice, sank. And even Perce, the youngest member of the stranded crew, knew there was no hope of rescue. If the men were to survive in the most hostile place on earth, they would have to do it on their own. Victoria McKernan deftly weaves the hard-to-fathom facts of this famous voyage into an epic, edge-of-your-seat survival novel.
