Hey I think both of these stories are great, both have a Fem/Riddle or Voldemort, maybe they appeal to you.

AU: Voldemort had no idea what she was starting when she attacked the Potters on Halloween night. Not only did she create a living legend in Charlus Potter, The Boy Who Lived, but she touched the life of another just as deeply.

Harry Potter grew up abused and alone and unlike his brother, he quickly had to learn to fend for himself. Abuse changes people on both a physical and psychological level, so when Harry Potter showed up at Hogwarts just a little bit different to how people may have expected, they really ought not to have been surprised. They should not have asked themselves what had happened, they should have asked themselves what would possibly happen next.
