Nessie and her faithful heroes the Four Craftsmen return to earth in Portal of Opportunity. They must sabotage more of the Enemy's End-Time plans... this time by extracting key players from the grip of darkness. But, deceiving a deceiver can be difficult... and there can be a steep price to pay. A child from war-torn Kandahar. A disciple of the original Twelve. A cosmic Navigator from a family of rebels... all these wait to pass through the Portal of Opportunity.
