The Penetrator wanted nothing more than to destroy the Mafia. But when his college roommate Tony Rossi, the son of Boston's most powerful Don, asked him for help, Hardin couldn't refuse. Somebody was masquerading as Mark's buddy, trying to take over the drug trade in Boston, and if the fake didn't succeed, Rossi's wife and son would lose their lives. Whatever it took, the Penetrator swore he would save the innocent - and make sure the corrupt could never harm anyone again.
