'Once, I was walking on a ridge and lightning was sparkling peaks to the east and the west, while a white spear of cloud hurtled straight for us. We found the top of the mountain, felt its texture through our boots, stared at the views, then turned and ran through an explosion of rain that was dark in the fury of its clouds, that swapped the sweat from our faces with its own jealous wet. Going was the only thing to do, but it still felt a terrible idea, because we’d have to leave the top of the mountain. There were still views. We could still see.' (Introduction)
