Wonderbook: Book of Potions

Zygmunt Budge left Hogwarts at fourteen and spent the next decades alone on a Hebridean island mastering potioneering—his resentment at being denied entry to the Wizarding Schools Potions Championship never fully faded. Five hundred years later, a Gryffindor student finds his annotated Book of Potions in the Hogwarts library and receives an unexpected tutorial from the author's lingering spirit—while somehow being entered into the very Championship Zygmunt never got to compete in. To win it, the student will need Sirius Black's help and the rarest ingredients available.
