Carina Riddle has only met her father once, and then only for a few seconds. Most people alive have no idea she even exists, and even fewer know who she really is.
She has never had even one friend, unless you include Draco Malfoy who was only there because they grew up together. Her past has haunted her her whole life. Since her father killed her mother she has been brought up by death eater's families, being passed from house to house like a possession.
She has only been taught to watch and learn, never to trust, and doesn't even know what love means.
(This is a Harry Potter fan fiction about Lord Voldemort's daughter. I take no credit for any of the characters or places used in the book. Anything that I mention that is in the books also is J.K. Rowling's alone.)
