A few days later at Grimmauld place

"Wow," Ginny said as she walked along the book shelves. "Those are old books," she said.

"Be carefully," Harry joked. "Not that you get possessed again."

"Not funny," Ginny said and gave him an slightly angry look. "Remind me to throw a quaffel at you at the next game." She then reads some of the book titles. "Some sound like really old magic. Not even dark magic or so. Just very old."

"Yeah," Harry said and noted a book in front of him. The title had been worn out but he could make out some of it. "Book of Lust," he mumbled and pulled it out. It seemed to contain spells of a more sexual nature. Harry looked up, wondering if Ginny had noticed it. She hadn't and so he dropped it into his bag.

"I gonna check on Kreacher quick," he then said.

"Sure," Ginny responded. She also had a book pulled out and read in it. A few minutes later they were ready to leave and meet their friends at the burrow.

"What was that book you read earlier?" Harry joked. "Hopefully not another diary."

This time he got a fist into his side. "If you joke about it again, Mr Potter," Ginny said, "then you can sleep on the couch for the rest of the summer."
