The Riddle Twins

Rhya and her twin Marcal are most unlike the other students at Howarts School of Witchcraft and Wizardry; while everyone is celebrating the disappearance of Lord Voldemort, they seethe through it. It is because of Harry Potter that they were left at their Aunt and Uncle's. And when the Malfoys' left them at an orphanage, they had only themselves to depend upon.
But when Rhya becomes friends with Harry Potter and Co., she will have to make a choice that had never confronted her before: Friends or Family? Death Eaters or those sworn against them?
The fact that her father is plotting to take over the world via a certain professor's head doesn't make the choice any easier.
