But he's still haunted by the suspicious deaths of his parents, who were the star performers in a radical traveling circus, the Mysterium. When he discovers that the Mysterium is re-forming in Barcelona -- without him -- he's devastated. But after learning that the Mysterium's enemies may be active in Barcelona, he rushes to warn his friends. Yet the circus isn't the safe haven Danny remembers. Could there be a traitor within the company itself? Why are the police after him? And who is the woman in a green coat stalking Danny? In this spellbinding sequel to The Black Dragon, if Danny wants to live long enough to find the answers, he will need all the skills his parents taught him. He senses that everything is linked to his parent's deaths ... and to the clues they left behind in this city.
