The shadow patrol

 by Alex Berenson. Tougher than Kevlar, John Wells is in Afghanistan for his sixth outing (after The Secret Soldier) in league with best-selling author and former New York Times reporter Berenson. Wells may suffer a bit of ennui from his killing lifestyle, but his high-octane adventure keeps his readers revved-up and racing to reach the end. The job is to track down a mole operating at the CIA station in Kabul. Soon, Wells realizes that heroin trafficking is at the core of the betrayal. Relying on nuances, a few bits of circumstantial evidence, and his own strong experiences, Wells lays and springs a trap with himself as bait. Verdict As real as the morning headlines, this thriller pours on the blood and guts but also traces the enigmas faced by men in a war zone. Berenson's special gift is to crank up the suspense until the armchair spy hollers for relief-and the next Wells installment.  -Library Journal (Check Catalog)
