AN: Again, please review!
It looked very old, and the cover was worn. The title wasn't visible.
She opened it to the first page, which normally had the Hogwarts Library stamp on it. There was nothing.
'This must not be a library book,' she thought. She flipped to the next page. It said, "Ancient Mind Penetration by Roberta Swallow".
'Mind penetration?' she thought, shocked. This reminded her of something that she had read about. . .Legilimency. She knew that it was very rare to find a skilled Legilimens. The only one she knew of was Lord Voldemort himself. 'But think of all I could find out with mind penetration!' she thought, starting to realize what this might mean. She could use this weapon not only for her own use, but she might be able to put it to use for the Order. The Ministry had banned people from teaching it long ago, but then again, this book looked pretty old itself. She sat down cross-legged on the floor.
Hermione flicked through the first three chapters, which were all about the history and theory of a type of mind penetration called Telepimency. She discovered that this branch of mind penetration would not just convey the person's mood and memories, like Legilimency, but their exact thoughts. Finally she got to the fourth chapter. Reading swiftly, she found what she had been searching for: the incantation used to see into other people's thoughts. She started to copy it down, but realized that this was not a library book, so she could borrow it without suspicion. Slipping it into her robes, she proceeded to check out the Transfiguration book, and hurried off to find Harry and Ron. Professor McGonagall would have dismissed the class by now.
'I've got to tell the guys,' she thought excitedly, but she could not help but listen to the voice at the back of her head that said, 'Maybe you shouldn't.' She paused and thought it over. It would be nice to tell someone of her discovery, but what if she wanted to use the incantation on Harry or Ron? They definitely wouldn't want to consciously let her into their brains. After a while she decided that it would be best not to tell them right away.
Hermione hurried through the rest of her classes and dinner, thinking about the book all the while. When she got up to Gryffindor Tower, the Fat Lady was having tea with another painting occupant, and Hermione gave her the password ("ice mice") and hurried through the portrait hole and up to her dormitory. She sat down on her bed and pulled out the book, turning to chapter four. She ran her finger down the page until she found what she was looking for. It read:
The incantation used for Telepimency must be performed while looking directly at the subject, but eye contact is not necessary. Once this is accomplished, you must say Adverto Penetro three times under your breath. Then, if successful, your mind will be filled with the thoughts of the subject until you choose to end the penetration, by saying Cease Penetro once under your breath.
'Okay,' she thought, 'Let's give it a try.' She tiptoed down the stairs to the common room, which was empty except for Neville, who was bent over a piece of parchment, quill in hand. She stared fixedly at him and muttered, "Adverto Penetro, Adverto Penetro, Adverto Penetro." Nothing. She tried again. "Adverto Penetro, Adverto Penetro, Adverto Penetro." This time, something popped into her head that was totally unrelated to anything: 'Flitterbloom. . .powder. . .is. . .poisonous. . .if. . .not. . .boiled.'
"Cease Penetro," she said quietly. She grinned. . .it had worked!
"Hello, Neville," she said loudly, walking over to him.
"Oh, hi, Hermione," he said, looking up from his work.
"What are you working on?" she asked, stealing a glance at his paper. The last thing written was, "Flitterbloom powder is poisonous if not boiled."
