Neal Cassidy's Daughter (OUAT) fan fiction

This story is about a girl who was adopted shortly after she was born, but just like her mother she was restless and was starting to realize she looked, acted, and had no similarities with her adopted family. One day she was snooping through her fathers study when her parents had gone out to dinner and her older brother was at a friend's house for a party. So when she stumbles upon a letter with an old Polaroid picture in it of 2 people she didn't know and she was confused and flustered. The letter said "To our little Girl when you find this please know we love you and what we did was for your best interest your father and I had no chance of keeping you or taking care of you, but we will never stop loving you our dear girl Love mom and dad". She just sat there in the study for a moment although it felt like hours maybe it was all she knew was that she needed to keep this letter and picture and find her real parents because she knows she doesn't belong with these people although she knew they loved her it just something was telling her in her bones that she didn't belong there.
