Harry, where ever you are, please come back. Everyone is worried, especially Ginny, Ron, and me.
-Hermione
Harry put down the letter that he had just received. But, this letter didn't mean anything to him; Harry could care less what people though about him. They hadn't cared when he was trying to make a difference. But, they wouldn't be as worried if they knew where I have been this whole time. Harry sat down on a nearby stack of books. His attempt to find the HBP's book was proving useless. He had been searching the room of requirement for weeks now, and had even gone as far as to disappear from reality to spend all his time looking for the book. At first, Ron and Hermione had tried to help him, but lost hope after only a short time.
Harry looked hopelessly around the room as a final attempt for the day to find the book. And with that, he left the room to only walk by the same wall several times before a door appeared. He walked in to find exactly what he was looking for; a place to sleep.
It had taken Harry quite a long time to find a way into the room where he had hid the book, but other than that, Harry considered himself an expert at controlling the room of requirement.
