Petra K and the Blackhearts take readers to a Prague-like city where miniaturized show-dragons are pitted against each other in secret, forbidden tournaments, and magic has been outlawed by a cruel child dictator. Here lives Petra K, the daughter of a shut-in mother, who becomes the master of a dragonka everyone wants to get their hands on. In a complicated world of sorceresses, Gypsies, child gangs, and secret police, Petra K needs to decide whom to trust, and whom to betray in order to keep herself and her pet safe. But revolution is in the air, and she too is caught up in its pull. Only the Blackhearts, a gang of orphan children, dare to defy the new dictator's rule, selling potions to survive. Along with the Blackhearts, Petra K faces a murderous pack of mechanical dragonka, a phantom secret agent-and, most harrowing, her own weaknesses. M. Henderson Ellis, the author of Keeping Bedlam at Bay in the Prague Café (New Europe Books), is a graduate of Bennington College and a Chicago native who currently lives in Budapest, Hungary.
