Fourth Wing (The Empyrean, Book 1)

No book-club edition documented. The confusion on this title comes from retailer and special editions rather than clubs, and several are actively mis-catalogued as firsts. The Limited/Holiday Special Edition (ISBN 9781649376169, 2023) is a different edition with new pictorial endpapers, black sprayed edges, gilt spine and two exclusive Xaden-POV bonus chapters — one dealer listing consulted offered it as "first edition overall," which it is not. Also distinct: the 2024 Limited Edition softcover (ISBN 9781649377371) with bonus content and sprayed edging. Reprint tells for the trade hardcover remain the number line and remainder marks.
