10,000 people jam the corridors of America’s largest shopping mall. 9,988 of them have come to shop. The other 12 have come to kill. <P>Stephen Hunter’s hyperdrive, eighth-gear thriller chronicles the day when the unthinkable happens: terrorists descend upon the heartland, opening fire in a Minneapolis supermall and executing innocent victims one by one. <P>Those on the upper floors, including retired Marine sniper Ray Cruz, take cover any way they can, but within minutes the gunmen have rounded up more than a thousand hostages. As it so often does, the story comes down to one man with a gun. <P>Except Ray doesn’t have a gun.
