Hermione Riddle- dramione.
A couple months after the war, Harry is dead, the death eaters killed Ron and are now looking for Hermione, but not for the reasons everyone thought. Lord Voldemort is now in power and now has an opportunity to get his precious daughter back. Draco is now a well trusted death eater yearning for Hermione's memories to come back so he can have the old Hermione back. His 'Mione. The dark 'Mione. Will she stay her old self or turn back the way she was and continue her life with Draco, Blaise, Theo, Pansy and Astoria? She will return to Hogwarts, now being owned by snape (he is alive in this) and will resume her seventh year turning to the slytherin princess.
