The Razor's Edge
by W. Somerset Maugham 

Larry Darrell had it made. He had a high-paying job lined up, he had a beautiful girlfriend who loved him dearly, he had supportive friends in high places. But there was one thing he lacked: a sense of purpose. He returned home after serving on the front lines of World War I to what seemed an empty life. During the war, he had seen some of his best friends perish-and for what? What makes the universe do cruel things? How can there be a purpose to life if we are born only to "drill and die"? 

Ever thought about just leaving it all to seek out something more meaningful? That's what Larry Darrell does. He travels all over Europe and Asia looking for meaning, and when he finally returns home, he doesn't have the ambition or the interests his friends do, but he has something else. He remains an enigma to his friends, but he now seems to know something that they don't—what is it?
