Recorded as a French-language work by Martial Caroff, *Les quatres saisons d’Ys* is represented here by a 2001 mass-market paperback edition of 190 pages. The title evokes Ys, the submerged Breton city of legend, and suggests a book-length fictional treatment in which myth, place, and seasonal change are central to the atmosphere. No subject, genre, or descriptive text was supplied with the catalog record, so the entry should be treated as a minimal authority/work record rather than a fully annotated summary. It is best suited to readers looking for French fiction with legendary or historical resonance, especially material connected with Breton folklore and the enduring image of a vanished coastal city.
