David Hagberg
David Hagberg is an American novelist best known for his techno-thrillers featuring super-spy Kirk McGarvey. Hagberg has also written numerous thrillers under the pseudonym Sean Flannery. Hagberg's style has been described as a cross between Tom Clancy and Ian Fleming. His thrillers generally feature a combination of technical detail, timely plots and super-spy heroics that are sometimes almost prophetic in their accuracy. In the novel Joshua's Hammer, for example, written in 2000, Hagberg gives a chilling account of a mega-terrorist plot by Osama bin Laden to kill thousands of Americans on their home soil, published a full year before the World Trade Center Attacks.
