The Queen Must Die (Chronicles of the Tempus Series #1)

The first entry in a magical, thrilling, time-traveling adventure trilogy

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-traveler in the city.
