What Books Have Influenced You?

Think of a book that had an impact on you.
When I was about fifteen, I read Of Human Bondage by W. Somerset Maugham and I was mesmerized. At the time, I was living in a town of a 1,000 residents in western Colorado where my father was a minister. My older sister, Alice,  had died in an automobile accident and I was struggling to make sense of that age old question: “Why do bad things happen to good people?”
I don’t remember now how I got my hands on Of Human Bondage or why I started reading it, but once I did, I couldn’t put it down.
