Near side of the precipice

the long version

"During FBI surveillance of a smuggling operation that originated in British Columbia, a large group of smugglers spring an ambush on the FBI team at a Seattle marina and get away with most of their cargo, leaving the FBI agents and many civilians dead or dying. When a large case abandoned by the smugglers is opened by the bomb squad, it becomes apparent that a terror attack is imminent. FBI agent Kate Seaman finds herself in a desperate search to prevent terrorists from using their weapons of mass destruction on yet unknown targets."--Cover [p. 4].
