This Year’s Theme: Spells and Potions

The theme for Harry Potter Book Day 2026 is Spells and Potions and what better subject to explore in the wizarding world?

Magic is, after all, at the very heart of everything in Harry Potter’s world. It takes countless forms across the seven books, from a simple Summoning Charm to a complex truth serum brewed in secret.

This year’s kit draws inspiration from the full breadth of spells, potions, and wandlore found in the series. Think:

• Accio — the Summoning Charm
• Veritaserum — truth potion
• The Marauder’s Map
• Invisibility Cloaks
• Wandlore & Ollivanders
• Polyjuice Potion

The event kit is filled with spellbinding ideas to help you explore, discuss, and celebrate the magic that makes the Harry Potter books so enduring. Potions and wands at the ready!
