Descendant.

Hermione had just finished the war and found out that her muggle parents weren't her real ones.
Her real parents were Daneel and Dean Novak, Pureblooded wizards.
Turns out Daneel was Tom Riddles younger sister, Daneel Riddle.
Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin. The problem with being a female Slytherin heir, is that they're cursed. Once they reach a few months before the age of eighteen, they body starts to convulse, and change into what their mother looks like. Another issue is that they must find a mate before their eighteen, or they'll die.

Hermione keeps this secret between McGonagall and herself.

But then to make matters worse, she starts to grow feelings for Draco Malfoy, her enemy since her first year.

What will happen when he is found out to be her mate?

Will she die? Or will she survive?
