Seventeen-year-old Katinka is trapped in a magical dress in the middle of New York City.
Ever since a man with burning blue eyes snatched her into his fancy flying carriage, Katinka has been a prisoner in the realm of the Magi, an invisible 18th-century world of haughty, aristocratic wizards, torturous corsets, and absolutely no chance of education for women. Which is very unfortunate since all Katinka wants is to get the education no women in her family have ever had.
Her kidnapper Balthazar, resident playboy of the Magi court, is locked in a battle of power with his formidable mother - the reason why he kidnapped "a filthy human" in the first place. As Katinka searches for a way back home, she finds Olivia, an autistic girl locked up in the house. Soon Katinka is busy solving Olivia's mystery, sending home magical letters, and trying not to trip in her gargantuan dress in front of a very charming courtier. It is most inconvenient, then, that the only person who can help her untangle the knots and find her way home is the man she has sworn to loathe for all eternity - Balthazar.
