Vatican assassin (Lulu.com)

BERNARD CAMPION'S friends call him "BC." Not that he has a lot of friends. You don't make a lot of friends when you're an assassin. His mission: eliminate the governor of Luna Prime, Meredith McEntyre. His bosses, The Office of Papal Operations: The OPO, tell him she's been sympathizing with the enemy, the Universal Islamic Nation (UIN). His boss? BC works for the Pope. IT'S 2109, a time of war. BC is "officially" assigned as PR man to the Vatican Mission on Luna Prime, the major city on The Moon, as his cover. Just a mild mannered, young, twenty-something priest working for the New catholic Church on public relations. But he's really a weapon pointed at the UIN żeby the NcC and their Earth based allies, the Universal Trade Zone, the UTZ.
