This is the story of Katie Berger-Jones-Burg. One minute, she's under the bed of her New York apartment, and the next she's in Buckingham Palace, at the height of Queen Victoria's reign-- a dangerous place to be. The Royal family is in mortal peril. In the secret passages of the palace, a plot is afoot. Suspicious figures huddle in the gaslit streets of London, and Katie is not the only time-traveller in the city.
