When Castles Fall (Drarry Slowburn)

It's been eight months since the Battle of Hogwarts and Voldemort's victory. The Boy Who Lived lost far more than just the war, including his sense of self, buried under layers of trauma and torture. As Draco's personal "servant," the only thing Harry knows now is survival.
Behind closed doors, the cold and calculated Death Eater he's ordered to serve is spiraling and tearing at the seams. Voldemort was never supposed to win, but Draco's worst fears came to fruition all the same. He gave everything to a cause that destroyed him from the inside out.
Until Harry's memories resurface, Draco will have to maintain a brutal, callous façade while confronting both the ruins he helped create and the dangerous feelings Harry develops for someone he was conditioned to obey.
