Described as a "thrilling, steam-punk, time-travel, adrenaline-fuelled adventure series, it's all that and more. The book opens with a recap, explaining Charles Smart's time tunnel to Victorian London and the FBI's WARP – Witness Anonymous Relocation Programme – plan "to stash federal witnesses in the past".
The reader is then whizzed to present-day London where Blessed Colonel Box has transformed the country into a police state. He enforces his rule with his Boxite army and his 'Thundercats', sisters Lunka Witmeyer and Clover Vallicose, nun-like women warriors who worship Box as their god.
