The hangman's revolution / Colfer, Eoin

FBI agent Chevie Savano escapes into the past to elude the secret police after they kill Charles Smart just as he is telling her of the W.A.R.P. program, and she and Riley team up to find Colonel Clayton Box before he can launch missles at the capitals of Europe.

Seventeen-year-old time-traveling FBI agent Chevron Savano finds herself traveling back to the past once again to prevent a man with knowledge of the future from taking over London.
