LEGO first released its line of book nook sets back in June of 2025 and they've been very well received. There are currently only three book nook builds available (from Lord of the Rings, Sherlock Holmes, and Harry Potter) and there have been little to no discounts on them until recently. The Lord of the Rings book nook was the first to drop in price earlier this month and now the Harry Potter edition has followed suit. The Hogwarts Express book nook was already the most affordable of the three builds. The Hogwarts Express Book Nook Drops in Price on Amazon
