Josephine Stanton, Madame and assassin, has received another assignment from her primary client, Her Majesty Queen Victoria. Granted, most of her jobs come from The Bureau of Steam Technology on her behalf, but she prefers to think of herself as working for her Queen. Content with her life, she sets up her mark only to have her entire world turned upside down and everything she's worked for put in jeopardy.
John Griffin, the Earl of Melton, is a man of many secrets. A former soldier, he was recalled from the life he loved in order to replace his father as Earl. But with the advent of steam technology, he has found a way to re-engage his analytical side--too bad its more controversial than is proper for a peer of the realm. Walking a fine line as he balances appearances he is not prepared for the beautiful woman who has come to kill him.
Neither of the pair expects the heat that steams them up between the sheets and ultimately sets New Victorian London on its ear.
