When Ophelia's sister disappears, there's only one way to save her. Ophelia must enter the Phantasma, a deadly competition inside a haunted mansion, and claim her prize: a single wish.

The Phantasma is a labyrinth of winding corridors and luxurious ballrooms, teeming with demons and temptations. Ophelia will face nine challenges, each more dangerous than the last. There can only be one winner, and the other competitors will stop at nothing to eliminate their rivals.

Every day, the house creates new monsters. But just when Ophelia's fears threaten to overwhelm her, a mysterious stranger offers her a deal.

Charming, arrogant, and irritatingly attractive, Blackwell claims he can guide her through the deadly evidence ahead. All he asks in return is ten years of her life.

Ophelia knows she shouldn't trust him. Blackwell doesn't seem dangerous, but appearances can be deceiving. Worse still, she feels a dark and irresistible attraction that draws them closer and closer.

Your life is in danger. But in Phantasma, the only thing more deadly than losing the game is losing your heart...
