"The Valley of Shadows, is a first-rate thriller, well-crafted and relentless, that launches like a rocket and never slows down. Mark Terry is at the top of his form, a slam-bang storyteller, and this novel about L.A. under attack from jihadists is not to be missed."

"Complex and gripping, The Valley of Shadows by Mark Terry is a sprawling tale of espionage, religious fanaticism, and the cost of hubris. With rich characters and superb insider details, it's a deeply satisfying novel that will linger with you a long time."

"Not since Thomas Harris's classic Black Sunday has a thriller so brilliantly captured the very real threats posed by modern terrorism as The Valley of Shadows. Mark Terry's terrifying tale reads like prophecy, warning and treatise all rolled into one. And the result is a ticking clock treat that's the very definition of a one-sitting read. Vince Flynn and James Rollins better watch their backs because Mark Terry is coming up fast!"
