Publisher's description

From the back cover: While a crucial peace conference fills Deep Space Nine with rumors of intrigue and conspiracy, Major Kira and Lt. Commander Worf embark on a dangerous undercover mission deep in the heart of the Gamma Quadrant. Their mission: to find the secret of the addictive substance that the Changelings use to control their Jem'Hadar warriors. But how long can Worf and Kira remain undetected in the midst of the Dominion? Odo may be their only hope; but to save them, he'll have to stand against his own people.


A Dominion scientist has discovered information on Jem'Hadar DNA, including how the Founders modify that DNA to make them dependent on ketracel-white. Seeing the opportunity to stop the Jem'Hadar threat, Sisko sends Worf, Kira and Odo into the Gamma Quadrant to retrieve the information.

On the station, Sisko is hosting peace talks between the Federation and the Cardassians and the Maquis. The talks are overseen by the Valtusians. Wary of Changeling infiltration, Sisko orders Bashir to test the DNA of the delegates, to make sure they are who they appear to be. Complicating matters is that the Cardassian representative is identified by a Bajoran vedek as a war criminal from the Occupation.

Background information

  • "The Heart of the Warrior" marks the first appearance of Worf in a Star Trek: Deep Space Nine novel, not counting the novelization of "The Way of the Warrior". The historian's note gives the name of the novel as The Trojan Spaceship.
  • John Gregory Betancourt commented: "Worf has always been one of my favorite characters, and I wanted to write a book about him but set in the Dominion, where he would find a challenge to his handto-hand combat skills. Unfortunately, later seasons of DS9 developed the Founders and Dominion enough that my book is, ah, retroactively contradictory to the official universe in a number of places". (Voyages of Imagination)

Related stories

  • The Changeling characters recall the events of "The Adversary", where Odo became the first Changeling to kill another.
