How it spread

Trace the origin

Early copies reached UK readers before the official launch. Fans gathered at midnight parties and discussed the book on Reddit and TikTok alongside paid billboards. BookScan tracked a record adult debut of 1.29 million US hardcovers. Fragrance tie-ins and reader awards followed.
