Cook the Books Club selection, hosted by Simona of Bricole, has been Red Sparrow by Jason Matthews. According to the Publishers:
"In contemporary Russia, state intelligence officer Dominika Egorova has been drafted to become a “Sparrow”—a spy trained in the art of seduction to elicit information from their marks. She’s been assigned to Nathaniel Nash, a CIA officer who handles the organization’s most sensitive penetration of Russian intelligence. The two young intelligence officers, trained in their respective spy schools, collide in a charged atmosphere of tradecraft, deception and, inevitably, a forbidden spiral of carnal attraction that threatens their careers and the security of America’s valuable mole in Moscow" .... The Publishers' rant also called the novel an "electrifying modern spy thriller", however stupefying might be a better adjective.
"The art of seduction" i.e trained and systematicaly degraded, prostitute spies. Sadly, I was unable to finish this book, couldn't identify with the lead characters at all, aside from pity, and would agree with one reviewer, admittedly in the minority, of mostly sycophant mainstream voices, who said in part:"If this was a novel about old spies in suits, I’D BE SO HAPPY.
