6/series. Ex CIA/loose cannon iron man John Wells revisits the country where he spent nearly a decade under cover: Afghanistan. This time, he’s not undercover as a Taliban fighter, but in Kandahar investigating possible American troop corruption. Among other things. Berenson (whose thanks page includes the pilots who took him along on recent patrols in the Afghan theater) brings an authenticity to his books that’s hard to match. The melding of internal and external lives is almost textbook perfect, and his portrayal of the stresses on our soldiers is at time heartbreaking. Never tell yourself that we do not suffer as a country when we go to war in a foreign place. We do, and our kids, our treasure, do even more. A 5, as always, the book is topical, very well-researched, and exciting.
