Sometimes escape is impossible. Sometimes love isn't eugh. 1913. Christmas Eve. Ardis hardly expects a quiet holiday with Wendel, between fleeing Constantiple and hiding from an ancient society of assassins. And they owe a debt to a certain archmage. In Konigsberg, Prussia, they work with Konstantin on the next evolution of Project Lazarus. Wendel once called Konigsberg home, the city w besieged by the Russians and their clockwork engines of war. This may be Wendel's last chance to save his family and find redemption, but he's tormented by nightmares and tempted by laudanum. Ardis fears her love isn't eugh to save Wendel. Her hands are full piloting the automatons, and she's terrified to tell him a secret of her own. Will they--and their love--survive the storms of war?
