When her sister disappears, Ophelia has only one way to save her: enter Phantasma, a deadly competition inside a haunted mansion, and claim the prize at stake: a single wish. Ophelia must face nine challenges, each more dangerous than the last, but that is not all. She must survive ruthless competitors ready to do anything to eliminate their rivals, tempting demons in opulent ballrooms, and twisting secret passages. Just when her fears threaten to overwhelm her, a mysterious Phantom offers her a bargain.

Charming, arrogant, and impossibly attractive, Blackwell claims he can guide her through the lethal trials. All he asks in return is ten years of her life.

Ophelia knows she shouldn't trust him, but she has no other choice, especially as a dark and irresistible attraction draws them ever closer. She must be very careful, for in Phantasma the worst thing to lose is not the competition, but her own heart...
