A Harry Potter Fan Fiction There was an unknown third child that Marvolo Gaunt-Voldemort's grandfather- had that even the two most powerful wizards of the twentieth century were unaware of. His name is Marcellus Augustus Pyrites. His granddaughter, Athena Ophelia Pyrites, is the Lost Heiress of Slytherin. This story will be an account of how her mysterious family began and where it is now- at Hogwarts School of Witchcraft and Wizardry. Athena is given a mission to befriend the boy with no choice, Draco Malfoy. Will she be able to choose between following her heart or following her unwavering loyalty to her friends and family? **I DO NOT OWN ANY OF J. K.
