The Dark Lord's Pet Princess

Larissa Black is the eldest child of Walburga and Orion Black. There is a lot of pressure on her, as she is a member of the proud and noble house of Black.
With her mother constantly on her back about finding a good husband, Larissa wants nothing more than to rebel.

She isn't too bothered about blood purity until she meets a mysterious and powerful dark lord, whom she is instantly infatuated with.
But what happens when her oldest cousin Bellatrix also falls for Lord Voldemort?
And if the dark lord chooses her, Larissa's life will never be the same again.
Loving bad people has always been a weakness of Larissa's, but loving the heir of Slytherin might be too much for even her.
