DracoxOC. Sky has been raised in secret by the Order of the Phoenix, because Voldemort has sought her since before she was born as his heir. When she's 16, a pair of Death Eaters manages to capture her and bring her to their fortress. After resisting a memory charm, Sky must rely on her ability to act, but everything turns upside down when she finds love where she least expects it.
