Harry Potter and The Blood-Soaked Succession

Ron and Hermione had died due to the events at Malfoy Manor and Harry was on track to join them. Alone and beaten, Harry resorts to the most horrendous magic to try and save his own life and continue the hunt for Voldemort's Horcruxi. An act that would start him on the path to becoming a monster so much greater and more terrible than the one he had set out to destroy.
