Prisoner of an Empty House

Narcissa Malfoy lies awake in bed, pondering how Azkaban changed two major people in her life, Bellatrix and Sirius and wondering how it would have changed Lucius. Most people think of her as cold-hearted, but there was nothing colder than her empty bed. But will that change? Also, Narcissa is a lot younger than her siblings and cousins. Rated for slight hurt of Narcissa.
