The Dashkova Memoirs

 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.
