Exile. Princess. Thief. After years of running from the Emperor of Russia's assassins, Ekaterina "Kat" Dashkova has finally found an unlikely home in Philadelphia under the tutelage of Benjamin Franklin. When a mid-level government official is found wandering colonial Philadelphia without his clothes—and his last two years of memories—Ben and Kat suspect otherworldly forces at work. Neither of them know that a dark revolution lurks beneath the veneer of civilization, ready to unleash its malevolent magic unless Kat makes a grim sacrifice.

Ignorance is bliss, unless the world is out to kill you... An investigation into a strange cauldron and a dead thief in Ben Franklin's parlor leaves Katerina Dashkova, Russian princess in exile, as the main suspect. With her memory damaged and Ben Franklin missing, Kat must navigate the treacherous waters of American politics to solve the mystery while ominous rumblings threaten to drag the country into a new war.

Katerina Dashkova must die. When Warden Simon Snyder seeks Kat's help to solve a bloodless murder, she becomes entangled with a prophecy that predicts her death on the Winter Solstice. The investigation turns an old friend into a dangerous enemy, complicates loyalties, and creates a mystery so deep that Kat will have to expose herself to ultimate betrayal to solve it. Even if she does, the question remains: Can she save Philadelphia from an ancient evil?

When Thomas Jefferson's longtime companion is murdered with dark magic, Katerina Dashkova and Ben Franklin must find the killer before the war-hungry Federalists learn the truth and use it to maneuver America into a war with Russia. Unfortunately, the unknown assassin isn't the only one causing a certain rusalka with a magical hold on Kat's future has made an impossible demand that will test her loyalty to her new country to its very limits.

Katerina "Kat" Dashkova has become a potent sorceress using her magic to help Ben Franklin and the Transcendent Society in the fight against Russia and the Otherworld forces that threaten the civilized world. But her powers are useless when a plague of monsters descends on Philadelphia, threatening to plunge America into chaos. As Kat searches for the source of the supernatural creatures, she encounters a mysterious benefactor offering favors for assistance, learns a dire secret that could doom the Society, and must face a contest against an unexpected foe from her past.

Things should be getting easier for Katerina "Kat" Dashkova. The former princess of the Russian empire wields considerable sorcerous powers, has learned to control the unruly prophecies in her head, and is a member of the Transcendental Society—a group dedicated to protecting the ideals of the Enlightenment from the tyranny of the supernatural—under the leadership of a quasi-immortal Benjamin Franklin. Except the god Veles has laid claim to her former homeland of Russia, and unless she can stop him, the world will be his next conquest. To reach Veles, Kat and Ben must travel through the realm of dreams in Baba Yaga's hut—a transdimensional craft owned by a trio of dangerous witches. The hut will help them reach their destination, but it contains dangers of its own, things that even the hut's mistresses have forgotten. Things that only need a little magic—or the whiff of prophecy—to escape.
