The Kremlin's Candidate by Jason Matthews (2018) Scribner 

Our heroine, the red sparrow, has become the head of the SVR, the spy ring for Russia and has found herself on the inside of Putin's closest advisers.  But her immediate boss suspects there is a mole at the highest levels.  Meanwhile, he has positioned a Navy Rear Admiral, whom he has used for a decade, to become the head of the CIA.
