A series of letters by a teenage student chronicles his reluctant transfer from a secular lycée to a Jesuit boarding school and his daily reactions, including nightmares, family conversations, and anxieties about discipline and identity. Through candid, youthful observations he examines preconceived prejudices about the Jesuits, sibling and parental influence, and the tension between imposed correction and personal growth. The epistolary structure follows early humiliation, moments of resignation, and a gradual willingness to judge by experience, offering an intimate account of adolescence, self-scrutiny, and the collision between rumor and firsthand observation.
