Buckingham finds himself thrown back into the covert world of intelligence where a play for power is underway. He'll have to decide where his loyalties lie if he's to intervene in a series of events that will threaten the whole nation.

Time is running out and lives are at stake; is there anyone Tom Buckingham can trust?
