Althea -- heiress to the Loviatar crime syndicate -- has been playing a cat and mouse game with the duke and head Jupiter agent Damien Reed for years. The phantom thief has stolen art, gems, secrets and gotten away without a trace. But the one thing she can't get away from is her father's control. So she has no choice but to accept when he offers up this impossible bargain: impersonate Damien's fianceé, take down Jupiter from the inside, and kill Damien in exchange for her freedom. All Althea needs to do is not get caught or fall in love with the duke in the process.
