America 1972. Bombs have been going off: in university labs, police headquarters, the U.S. Capital, the Pentagon. In California, shootouts with police are weekly. And the Black Liberation Army is about to join with the Weather Underground in a spree of hold-ups to fund the coming revolution. Then, in downtown Boston, the killing goes wholesale when a dynamite bomb shatters the Prudential Center. Martin Trepan of TASK has to find the bombers and wonders if the disappearances of college professors and students is part of puzzle. The beautiful, dangerous Mi-Sun Kane thinks so--and is determined to find her daughter before Trepan does.
