Phantasma

When Ophelia's sister disappears, there is only one way to save her. Ophelia must enter Phantasma, a deadly contest inside a haunted mansion, and claim its prize-a single wish. In a maze of twisting corridors and lavish ballrooms, Ophelia will face nine challenges, each more dangerous than the last. Just as fear threatens 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. Ophelia knows she shouldn't trust Blackwell. Worse still, she feels a dark and irresistible attraction drawing them closer and closer. And in Phantasma, the only thing deadlier than losing the game is losing your heart...
