Harry and Hermione were working in the library at Grimmauld Place on day, replacing books on the shelves, when suddenly a book near Harry started glowing.
“Hermione, why is this book glowing?” Harry called nervously to his best friend.
“Where is it?” she called back distractedly, not looking up from her notetaking. She was keeping a running list of the books they were studying, so that their friends would know what books were actually safe to take off the shelves whenever they visited.
“Over here, a few feet from where I’m standing. I don’t know what the subject is, but it’s glowing with a bright white light.”
“Go over and pick it up,” Hermione instructed. “Read the title.”
“I’m not picking it up, you pick it up! Have you forgotten who used to own these books? I’m not picking up anything in this house that glows like that, there’s no telling whether it’s cursed or not! You’re welcome to do so, if you like.”
“Boys!” Hermione muttered, stomping over to the shelves. “Alright, where is it?”
“Right there,” Harry said, pointing. Hermione found the book and pulled it off the shelf, tilting the volume in an attempt to see the title printed on the spine.
“The Lord of the Rings, by JRR Tolkien. I always wondered if he wasn’t a wizard,” Hermione mused.
“Ha ha, very funny. I cannot see the pureblood bigoted Blacks owning a copy of Tolkien’s work, whether he was a wizard or not,” Harry retorted. “What’s it really say?”
“The Lion, the Witch and the Wardrobe, by C.S. Lewis.”
“The Wonderful Wizard of Oz, by L. Frank Baum.”
“Most Potente Potions.” Hermione was laughing merrily at this point.
“Give me that thing!” Harry exclaimed, exasperated. “The Marauders Book of Pranks, by Messrs. Moony, Wormtail, Padfoot and Prongs…well that explains why it was glowing, it was trying to let the next generation know it was here. Looks like the current generation is going to have a female in it,” he remarked, shooting a look at Hermione, who smirked.
“The Chronicles of Prydain by Lloyd Alexander,” she said, grinning wickedly. “In one volume.”
Harry narrowed his eyes at her. She laughed and took off running, with Harry hot on her heels. “Get back here! Just wait till I get my hands on you…The Chronicles of Prydain, honestly!”
