America is reeling; Al-Qaeda has struck and thousands are dead. The country scrambles to respond, but the Pentagon has no plan for Afghanistan--where Osama bin Laden masterminded the attack and is protected by the Taliban. Instead, the CIA steps forward to spearhead the war. Eight CIA officers are dropped into the mountains of northern Afghanistan on October 17, 2001. They are Team Alpha, an eclectic band of linguists, tribal experts, and elite warriors: the first Americans to operate inside Taliban territory. Their covert mission is to track down Al- Qaeda and stop the terrorists from infiltrating the United States again. First Casualty places you with Team Alpha as the CIA rides into battle on horseback alongside the warlord Abdul Rashid Dostum. In Washington, DC, few trust that the CIA men, the Green Berets, and the Americans' outnumbered Afghan allies can prevail before winter sets in. On the ground, Team Alpha is undeterred. The Taliban is routed but hatches a plot with Al-Qaeda to hit back. Hundreds of suicidal fighters, many hiding weapons, fake a surrender and are transported to Qala-i Jangi--the "Fort of War."
