Welcome to Phantasma. There are only two rules to the game: Stay alive. And don't fall in love. When Ophelia's sister disappears, she must enter Phantasma, a deadly competition inside a haunted mansion, to claim its prize: a single wish. The mansion contains nine challenges, each more dangerous than the last, with only one winner. A mysterious stranger named Blackwell offers her guidance through the trials in exchange for ten years of her life.
