Mark Greaney returns to the program today. We’ve discussed his co-authoring some of and continuing Tom Clancy’s legendary Jack Ryan thrillers. He’s also written a best-selling military thriller with retired Marine Lt. Colonel H. Ripley Rawlings IV, entitled, Red Metal. But most readers know Mark for his successful Gray Man series starring burned CIA operative, Court Gentry. We’ll be talking about his 11th installment in the series, Sierra Six, which is now available from Berkley.
