From the book
Title: Of Human Bondage by William Somerset Maugham Description: Of Human Bondage is a moving exploration of loneliness, obsessive love, and a young man's search for meaning and direction in life. Written in the third person, it tells the story of Philip Carey, a self-conscious orphan with a club-foot who learns medicine. Not only is this a significant work in the Bildungsroman tradition, but its largely autobiographical basis gives it a special interest in view of the exceptional public success that Somerset Maugham was to enjoy over several decades.
