The book for November is Once a Spy (Spy #1) by Keith Thompson. 

"When Charlie Clark takes a break from his latest losing streak at the track to bring home his Alzheimer’s-addled father, Drummond, they’re attacked by two mysterious shooters. At first, Charlie thinks his Russian “creditors” are employing aggressive collection tactics. But once Drummond effortlessly hot-wires a car, Charlie discovers that his unassuming father was actually a deep cover CIA agent . . . and there is extremely sensitive information rattling around in his troubled mind. Now the CIA wants to “contain” him, so the two embark on a wild chase through the labyrinthine world of national security that will force them to confront unspeakable danger, dark conspiracies, and what it means to be a father and son."
