Nathan M. Farrugia is an Australian author who writes action thrillers with a science fiction edge, centered on covert operatives caught between shadowy organizations and experimental technology. His books move quickly and favor high-stakes physical action alongside conspiracies that involve genetic programs, engineered soldiers, and agencies that shouldn’t exist but very much do.
He has two main series. The Fifth Column follows Damien, an operative who discovers he’s been working for the wrong side, while the Helix series builds out a connected world with a different cast and slightly more science fiction emphasis. Both series reward readers who like their action thrillers with conceptual ambition rather than just procedural momentum.
Farrugia is a self-published and hybrid-published author who has built his audience largely through digital channels and genre conventions, and his output reflects a writer who understands what fans of the genre want. The books don’t slow down for long, and the conspiracies stay complicated enough to stay interesting across multiple volumes.
