A Forbidden Birthright

It's ten years after the Battle of Hogwarts and Hermione Granger is a successful author, and is head of Gryffindor House under Headmistress Minerva McGonagall.
Still navigating the lingering effects of the war while working on her next book, Hermione is forced to reveal a secret and finds herself falling for rival Hogwarts teacher and head of Slytherin, Draco Malfoy.

Draco, per McGonagall's suggestion, teaches Defense Against the Dark Arts. Although his reputation precedes him, he is determined for his students to respect- or fear- him. But it's Hermione's respect that he wants the most, despite his cold and unflinching exterior.

Their tentative romance is darkened by the growing rumors of a rising dark power, and suspicions rise that former Death Eaters like Draco will be called to it.

And answer.
