"On the busiest shopping day of the year, some idealistic college students stage an elaborate media stunt at the largest mall in America. They believe that jamming devices in their backpacks will disrupt the stores' computer systems, causing delays and chaos. But their backpacks are stuffed with explosives, ready to be detonated by remote control and turn them into suicide bombers. Called to the site, FBI profiler Maggie O'Dell's task becomes personal when a tip reveals that one of the college students involved is her brother." --Cover, p. 4.
