Hating them has never felt so sinful …

My half sister died at the hands of a friend, and I vowed to make him pay.
In the midst of a brewing war between two rival families, the mysterious and friendly Grey Westbrook sweeps me off my feet when I need it the most.
However, my childhood friend Levi Torres—now an obsessive, vicious boy—has made it his mission to erase him from my life.
His arrogant and hedonistic cousin Apollo Torres offers protection against Levi's wrath if I agree to all his filthy demands. But Levi and Apollo aren't my only problems …
A ghost of the past is hunting me, promising sweet vengeance, and the temptation is too big to resist.
My body is ravished and ruined, and I don’t want the depravity to stop, even if my stalker is someone I know.
Three jealous, insatiable boys who were there that night still fight to own me … Betray me.
One is a killer.
One is a sinner.
One is a big, fat liar.
And I will expose them all.
