Firefly – A Fairytale, authored by renowned fashion designer Ritu Beri, is the most expensive Indian book, priced at ₹1 lakh. The book was self-published by Beri after Penguin India dropped the project due to its high pricing. This exclusive collector's item explores themes of architecture, history, femininity, and Beri's Parisian experiences that shaped her global fashion career.

The foreword is written by François Lesage, the legendary embroidery artist from France. Only 100 limited-edition copies are available, making it a rare luxury piece. In India, the book is sold exclusively at Ritu Beri's store in Delhi, and internationally at the Louis Vuitton flagship store near Champs-Élysées in Paris.
