After thwarting the violent, international, fascist syndicate known as Nemesis, Evan Ryder returns to Washington, D.C., to find her secret division of the DOD shut down and her deceased sister's children missing. Now the target of a cabal of American billionaires who were among Nemesis's supporters, Evan and her former boss, Ben Butler, must learn to work together as partners -- and navigate their intricate past. Their search will take them from Istanbul to Odessa to an ancient church deep within the Carpathian Mountains of Romania. And all along the way, an unimaginable enemy stalks in the shadows, an adversary whose secretive past will upend Evan's entire world and everything she holds dear.
