Franny and Zooey is a 1961 book by J.D. Salinger that collects two stories, "Franny" and "Zooey," focusing on the two youngest members of the precocious Glass family as they grapple with spiritual and existential crises. The book explores themes of authenticity, disillusionment, and the search for meaning, as Franny experiences a breakdown and her brother Zooey tries to guide her through her spiritual and emotional turmoil, drawing on Eastern religions and mysticism.
