It was May 19, 2012 and a young and determined Canadian was proudly standing on top of the world after an agonizingly slow climb up Mount Everest. Shriya Shah-Klorfine had reached the summit. But in the hours that followed, things would go dreadfully wrong and she would perish, like hundreds before her, high up in Everest's "Death Zone." Since Edmund Hillary and Tenzing Norgay's first ascent of Everest almost 60 years ago, it has been an irresistible fascination for aspiring mountaineers. Hundreds make the attempt every year, and many don't make it. This year was no exception as hundreds made their way to the summit even as worrying signs pointed to trouble. Among them was Shriya Shah-Klorfine, the cheerful and energetic Torontonian. She had never climbed a mountain before, and despite warnings from her friends, husband, and seasoned Everest sherpas, she was climbing the world's highest peak, determined to succeed.
