It's called "Daughter of Darkness" by V.C. Andrews.
This book was just aweful. It's about a 17 year old vampire girl named Lorelie Patio (Mary Sue alert!) whos only purpose in life is to be her Daddy's sex slave. This book is filled with shallow evaluations of beauty, anti feminism, poor morals, and disgusting turn of events.
Lorelie has three sisters who are manipulated and emotionally abused by their father. The worst thing about it is that it's never seen as a bad thing. It's disguised as fatherly love. None of the characters recognize the manipulation or abuse. You have to read between the lines to pick up on it. It's almost identical to Twilight here, but at least Bella snapped back at Edward a couple times. Lorelie's father kills her boyfriend and she says "Oh, he's just protecting me because he loves me." She doesn't even get upset.
Literally every other page we're told how beautiful Lorelei is, and half the time it's Lorelie looking in a mirror thinking about how beautiful she is, then she starts complaining that her beauty is a curse because it makes too many boys notice her. Her beauty is so horrible that her teachers even lust after...
