‘Magical Water Plants of the Mediterranean’

Harry Potter and the Goblet of Fire
Miraphora Mina and Eduardo Lima have designed a huge range of books for the Wizarding World, ageing them, adding text on the interior pages, and sometimes even handwritten notes to make them feel more realistic. This book was given to Neville Longbottom by Barty Crouch Junior. Its information about Gillyweed would prove invaluable during Harry's Second Task of the Triwizard Tournament.
