Ninety days of darkness

Voldemort was triumphant and Hermione Granger has been a prisoner in Malfoy Manor for three months. At Voldemort's behest she is engaged to a reluctant Lucius Malfoy. Hermione is not easily subjugated and ninety days in the dark can change a person beyond all recognition. AU. Rated M for sexual content and violence, as dark as I'm every likely to get - still not that dark!
