CBS News The Book Report: Reviews from Washington Post critic Ron Charles (February 28) By Washington Post book critic Ron Charles This cold winter has delivered a long shelf of fascinating new books. Here are just a few you might enjoy: Grove Press In 2015, Viet Thanh Nguyen published his first novel, "The Sympathizer," about a communist spy who flees Vietnam after the Fall of Saigon and leads a double life in America. That fantastic novel won a Pulitzer Prize for fiction. Now, Nguyen is back with a sequel called "The Committed." It picks up with the next chapter in the life of a conflicted spy who's remade himself yet again, this time to work for a brutal crime boss in Paris.
