Kaplan returns a decade later and brings to life a lawless frontier. What he reveals is astonishing: teeming refugee camps on the deeply contentious Pakistan-Afghanistan border; a war front that combines primitive fighters with the most technologically advanced weapons known to man; rigorous Islamic indoctrination academies; a land of minefields plagued by drought, fierce tribalism, insurmountable ethnic and religious divisions, an abysmal literacy rate, and legions of war orphans who seek stability in military brotherhood. Traveling alongside Islamic guerrilla fighters, sharing their food, observing their piety in the face of deprivation, and witnessing their determination, Kaplan offers a unique opportunity to increase our understanding of a people and a country that are at the center of world events.
