Harry Potter and the Secrets of Willow

I looked into the green eyes of this stranger-eyes that matched mine. He smiled at me; a smile so warm it made me want to weep.
"Hello, Willow," he said, using the name I'd been given by the dragons, "I'm Harry, your older brother."
Then, the warmth from his voice added to that of his smile's really did make me weep, and I felt a small void I hadn't known existed inside me repair itself as he, too, began to cry.

This is the story of Lillas Potter, who goes by Willow since it was the name given to her by the dragons that raised her, the long lost sister of Harry Potter no one knew existed. This is her journey as she finds a family she hadn't known she had, a life she didn't know she could live, and an unlikely love she'd never once hoped to dream was possible...
*Note, the first chapter (Prologue) is in third person point of view, all the following chapters will be from Willow's (Lillas). Takes place after 7th book.
