The stone transformed immediately. Instead of a dull, granite rock there was now a lush, marble white headstone leading down a vast set of white steps to a door not visible from the surface. The headstone was inscribed with ancient text of Celtic Runes. Harry grinned widely. It was the second such grin he'd allowed himself in the space of a few days ... he dared not think about the other one, as he sat at Hermione's beside, watching her sleep. It was a guilty indulgence. She'd berate him if she ever found out. But he couldn't resist just one look, even if it had lasted for several hours.
