Juliana Del Rio is an EPA engineer who never ventured past the lab and courtroom. A true environmentalist, she wants to do more and joins the criminal investigations unit of the EPA in an unusual cooperative arrangement with the FBI s new Environmental Crimes Unit. With very little training, she is teamed with Sean Ryan, an aging narcotics FBI agent, who thinks his career is over when he is transferred to the FBI s new ECU. On their first assignment together, they must pose as husband and wife on an Alaskan cruiseliner to gather evidence of toxic dumping. But they soon face more danger than either bargained for, when they discover that the ships offer good cover for the transport and dumping of all kinds of toxic materials, including the fuel for weapons of mass destruction. Sean and Julie must overcome their differences to stop nuclear terrorists before they turn Alaska into another Chernobyl.
