Boston Bust-Out (The Assassin Book 3)

Robert Briganti is the Assassin. Ruthless, indifferent to his own survival, he lives only to destroy the Mafia. This time, armed again with a private arsenal of handpicked superweapons, he mercilessly stalks his enemies in Boston: a vengeance hit that backfires into a bloody double cross and a no-exit syndicate death trap that Briganti knows he has to enter—or die.
High-octane action-adventure in the grand tradition of Don Pendleton’s THE EXECUTIONER!
