Mistress of the Dark Lord

Bellatrix Black Lestrange is 46 years old, a little mental, devoted to the Dark Lord... and pregnant.
When Bella cannot control her emotions as she used to, she looks to her sister for advice. No, not Narcissa. Andromeda. Even though they're estranged. But when they consume too much wine, Bella reveals something she never meant to - something dangerous to reveal.
Then, after defying the Dark Lord, Bellatrix is tortured by her lover within an inch of her life... but remains convinced he loves her. He must. He wouldn't have given her the gift of their child if he didn't. Overwhelmed by conflicting emotions and bitter about the assault, Bellatrix is confined to bed, confronting her demons alone.
She eventually gives birth at Malfoy Manor to a premature but healthy baby and is thrust into a role she'd never imagined she'd embrace so fully: motherhood.
Finally, clutching her infant daughter, Bella sneaks away, though she should be awaiting her Master's wrath after the Golden Trio stole Hufflepuff's Cup from her vault, to seek assistance from a man she loathes but, most unfortunately, needs: Hogwarts Headmaster Severus Snape.
She lives for the Dark Lord. Will she die for him?
