Inevitably Collin (an H.P fanfic)

She grew up with nine other siblings, all of them unrelated to her. Outcasted and taunted by her own family, she isn't very prepared to meet and greet people. But when a letter arrives delivered by a very humongous owl, her whole life makes a change for what seems to be the great, the good, the bad, and the worse.

(I do not own Harry Potter. I only own characters that I created myself. The rest of the rights go to J.K. Rowling. This book follows that of the book series, some of which also goes with the movies)
