American author of many Star Trek novels, among them the Destiny trilogy, who also co-wrote two episodes of Deep Space Nine, Starship Down and It's Only a Paper Moon.
David Mack is an American novelist who has written Star Trek fiction for more than two decades.
His first professional Star Trek work was for television. With John J. Ordover he wrote the teleplay of Starship Down, a fourth-season episode of Deep Space Nine in which the Defiant is crippled inside a gas giant, and the pair supplied the story for It's Only a Paper Moon in the seventh season, in which Nog retreats into Vic Fontaine's holosuite programme after losing his leg.
In print he is best known for the Destiny trilogy of 2008, which revealed an origin for the Borg and reshaped the continuity of the novels, and for his part in creating the Vanguard series. He has since written novels tied to Discovery and Picard.
