J.D. Salinger's masterpiece, The Catcher in the Rye, follows Holden Caulfield's journey after being expelled from Pencey Prep. He grapples with feelings of loneliness, depression, and a cynical view of the adult world, particularly what he perceives as "phoniness." Holden attempts to connect with various individuals, including his former teacher Mr. Spencer, an old friend Jane Gallagher, and a prostitute, but these interactions often leave him feeling more isolated. His eventual return home leads to a significant encounter with his younger sister, Phoebe, who provides a moment of genuine connection amidst his disillusionment.
