Phantasma: A dark fantasy romance

Phantasma is a maze of twisting corridors and lavish ballrooms, of demons and temptations. Ophelia will face nine challenges, each more dangerous than the last. There can only be one winner, and the other contestants will stop at nothing to eliminate their rivals.
Every day the house creates new monsters. But just as Ophelia’s fears threaten to overwhelm her, a mysterious stranger offers her a bargain.
Charming, arrogant and infuriatingly attractive, Blackwell claims he can guide her through the lethal trials ahead. All he asks in return is ten years of her life.
