Anya Karekanova returns to conclude the arc begun in the previous two books. Her mission in Japan has been successfully concluded, and she's finally free to return home to her beloved master. Except, when she gets there, he's not there. No one is. The palace has been destroyed. The servants have been slaughtered. Her allies, scattered to the wind. The only person left is Grace St Michaels, the former Cabalist that had somehow become her friend. The time has come for Grace to fulfil her promises. She's there when Anya needs her most - and so is the Cabal.
The Cabal know who is responsible for the attack, and they know where Viktor is. He has been arrested for violating the Immortelle Accord – the very agreement that he had helped to establish nearly four hundred years earlier. Anya knows he is innocent, but someone very high ranking in the clan must have fabricated convincing evidence against him.
She finds herself facing a terrible choice. On the one hand, she could choose to leave her master to his fate. He would be executed, and she would inherit all the wealth and power that had once been his. Or, she could risk her own life to try and save him. Will she choose love, or ultimate power? Whichever one she chooses, it will change her life forever.
