His Favorite Sin

'Why did you kill him?'
'Because he wanted you,' he replied without hesitation. 'And I am frightfully selfish with you, Miss Dahlia.'

They say we inherit the sins of our fathers - their curses too.

Dahlia Bell once worked as a live-in assistant to a blind teen, Lance Dvorak - a quiet boy with a black cat in his cold mansion. His family was surrounded by mysteries and murders she could never quite unravel during her stay with them. There was just something unearthly about them, but before she could discover more, she came across Lance committing a gruesome murder, and her whole world tipped into chaos. Dahlia, thinking she was next, fled the town for her life, never looking back, knowing that if he ever found her, she would be dead.
Almost seven years have passed; she lives as Cora, an unknown writer in a big city. She was safe from her past, it seemed, and getting her life together. Or so she naively thought, until one night, when it seemed like all her dreams were coming true, she unexpectedly encountered her haunting past in the form of Lance Dvorak.
The sweet kid she once knew finally has his mask down, and she can see the evil that had been lurking behind those eyes all this time. But mixed with all that evil was an obsession, one he wasn't willing to let go of even after so many years had passed. He had found her and was going to kill her, eliminating the only witness to his crime. Or was Dahlia wrong about what his obsession was about?
