The Silver Skull — Anne Renwick

An illegal border crossing. A fake marriage. A mad German count determined to create an army of unbreakable soldiers.

Lady Olivia is not all she seems. Trained for marriage to an assigned political target, her skills lie in programming household steambots to serve tea, dress her hair... and sound the alarm while she picks locks and listens at doors. Humiliated by a failed assignment, she decides to redeem herself by tailing a suspected double agent.

Lord Rathsburn must flirt with treason. Struggles to cure a horrible disease have met with unexpected complications. The cells he engineered can make a man's bones unbreakable, but the side effects are fatal. He believed the research terminated... until his sister was kidnapped by a German count. Her ransom? A cure.
