Bec McMaster is quickly making a name for herself with edgy, innovative steampunk romance. In this third book of her Whitechapel series, Sir Jasper Lynch, Master of the Nighthawk guard, has to find the revolutionary leader threatening the aristocracy--little knowing his target is his very own secretary.


In the mist-shrouded streets of Victorian London roam vampires, werewolves, and the clockwork army of the ruling Echelon class. And the one who watches over them all:
the Nighthawk.


Determined to destroy the Echelon she despises, Rosalind Fairchild has been masquerading as the revolutionary leader known as Mercury. When her younger brother goes missing, Rosalind poses as a secretary in order to infiltrate the Nighthawks and find their leader, Sir Jasper Lynch.
