An elusive woman arrives at Criminy’s doorstep with a steamer trunk, begging for a position in the caravan to perform her unique new act. She opens her trunk to reveal a menagerie of brilliantly colored butterflies. The woman, who calls herself Madam Morpho, is on the run from a dark past in London, where she was forced to leave her equipment behind and abscond with only her tiny performers. Playing a hunch, Criminy hires Madam Morpho on the spot. Taking her down to meet Mr. Murdoch, the reclusive talented engineer who keeps the carnival’s clockworks running, Criminy instructs them to work together to design and build a groundbreaking new circus for the butterflies. Amid the magical ambiance of the circus and the hint of danger from Madam Morpho’s pursuers, she and Mr. Murdoch soon find that their scientific collaboration has produced chemistry of a more romantic kind.

    Plucked from the streets of Manhattan and frightened half to death by a freaking Olympian god.And now I'm trapped in the Underworld, being forced to compete in a series of deadly trials for the position of Queen of the Underworld.

Who the hell wants a husband at all, let alone one made of smoke and riddled with death?I have to get back home, to New York and my brother. But I can't leave without completing the trials and they've been designed for a godly Queen, not Persephone - barista and botanical garden enthusiast.I'm surrounded by lethal, all-powerful maniacs.

But then what? And why, why, why am I so desperate to see under Hades smoky exterior and find out what he's hiding from me?If I win the trials, I have to marry the devil himself. But losing might mean losing my life.

    Sure, everyone sent to prison says that. It’s true, though. I’m not who they say I am. Dark. Evil. An abomination. The worst of the worst. They sent me to the deepest, most awful catacombs of Nightmare Penitentiary. It’s where they put all their secrets they don’t want anyone in the world—both human and paranormal—to know about. I’m left to be forgotten and waste away until the day I die. And I’m not alone. I’m there with others. Others who are worse than me. Terrifying. Horrible. Monsters. Four demons in particular who seem to wake from their evil slumber the moment I enter their presence. They want me. All four of them. I’m not sure what they plan on doing once they get their hands on me. But one thing’s for sure… It won’t be good.
