She was ordinary. As a Muggle, she was painfully aware that there were parts of his life she couldn't have access to. But she was an obstinate girl, and she clung to this extraordinary feeling she had for that brooding, cynical, marvelous boy.

He's the Boy who Lived. She's fifteen and unaware that she's a witch. After a chance meeting and a scuffle with dementors, she is swept into the wizarding world, where the two find adventure, friendship, betrayal, and more. Begins in the fifth book.
