Although Alex is disillusioned and unwilling to go back into the myths, Cleo hasn't given up hope. Researching, she reads about the Oracle of Delphi and thinks that if they go to her, they might find out something about their dad. Alex doesn't want to co-operate so she goes in herself and finds herself only to find that Cleo isn't a pilgrim but rather the Oracle herself. But when she has a vision of her own death by her guards, it becomes a race against time to find the scroll and escape.
