When Elizabeth Harper enters an arranged marriage to become Countess of Daverley, little does she imagine the challenges that lie ahead. Her fiery temperament sets her against one of the country's most vindictive characters, the Marquis of Kolerington. He is more than just a courtier, though. He has a powerful secret organisation, Nexus, behind him.

Soon, dark shadows reach out from the Daverleys’ Civil War past. Elizabeth, and the husband she has grown to love, are dragged into a desperate struggle for survival.

Overcoming one enemy, they vow to bring down the secret organisation that is threatening London with vicious crime and political unrest.
