Karim is twelve. He crosses the desert with his grandfather Idris and four camels. Idris says, "The wind draws on the sand. Keep the wind on your left cheek." A sandstorm comes. Idris is ill and falls from his camel. "Karim, you must lead," he says.
Karim ties the camels in a line. He walks all night. The wind is on his left cheek. In the morning he sees palm trees. The oasis! "Who taught you?" Idris asks. "You did, Grandfather."
