Deep Attack — Don Pendleton

SILENT RUN
A new drug conduit is funneling record quantities of cocaine through the Florida Keys to America's streets by means unknown. Mack Bolan's hard probe uncovers a threat that escalates the drug war to a disastrous new level: mini submarines deployed from large cargo ships.

Bolan becomes a moving target on two coasts as he wages war against a death machine financed by a narcobaron whose fortress in Colombia and army of killers have made him believe he's safe from the reach of justice.

The Executioner will prove him wrong.
