Lost Key begins with Corporal Harry Parker dropped into Cuba to fight Castro with the ill-fated counter-revolutionaries, then takes a much more experienced and retired Army Colonel Harry Parker from his Washington DIA office to revisit the seamy side of Tampa's Ybor City, drawn into the middle of a drugs-for-arms transaction. Not just guns, this time the stakes are higher - his family is in jeopardy, a nuclear weapon stolen by fanatical terrorists, the beginning of a wild ride across today's South Florida and the Florida Keys where romance with a member of the Conch Republic threatens to sidetrack his mission.
