Far in the future, 60,000 light-years from Earth, a loose confederacy of Terran exiles are locked in battle with the enigmatic Protoss and the ruthless Zerg Swarm. Each species struggles to ensure its own survival among the stars in a war that will herald the beginning of mankind's greatest chapter - or foretell its violent, bloody end.

Jake Ramsey - an unassuming yet talented archaeologist - has been given the chance of a lifetime. Hired to investigate a recently unearthed Xel'Naga temple, he knows this latest assignment will open up whole new possibilities for his career. Yet when Jake discovers the remains of a long-dead protoss mystic, his hopes and dreams are irrevocably drowned in a flood of alien memories. Bonded to the spirit of the dead protoss, Jake has become the sole inheritor of the protoss' total history - every event, every thought - every feeling. 

Sixty-thousand light-years from Earth, the corrupt Terran Confederacy holds the Koprulu sector tightly in its tyrannical grip, controlling every aspect of its citizens' lives. One man dares to stand up to this faceless empire and vows to bring it to its knees: Arcturus Mengsk - genius propagandist, tactician, and freedom fighter. A monstrous act of bloody violence sows the seeds of rebellion in Arcturus, but he is not the first Mengsk to rail against such oppression. Before Arcturus grew to manhood, his father, Angus Mengsk, also defied the Confederacy and sought to end its reign.

For the poor, hardworking citizens of the Confederacy's fringe worlds, the Guild Wars have exacted a huge toll. Swayed by the promise of financial rewards, a new batch of recruits joins the fight. Eighteen-year-old Jim Raynor, full of testosterone and eager to make things right at home, ships off to boot camp and finds his footing on the battlefield, but he soon discovers that the official mission is not what he's really fighting for.

The sinister zerg leader no longer commands her legions of bloodthirsty aliens against the humans of the Koprulu sector, all thanks to the combined courage and tenacity of Jim Raynor, General Horace Warfield, and a mismatched team of Dominion soldiers and outlaw rebels.

Since the beginning of time, the angelic hosts of the High Heavens and the demonic hordes of the Burning Hells have been locked in a struggle for the fate of all creation. That struggle has now come to the mortal realm...and neither man nor demon nor angel will be left unscathed.... 

Dominion ghosts epitomize the height of terran evolution and physical conditioning. Augmented by technologies that harness their innate psionic potential, these lethal operatives use telepathy and other superhuman powers to isolate and destroy the enemies of the Dominion. But when the hunters become the hunted and ghosts start disappearing without a trace, even the most dangerous human soldiers in the Koprulu sector have something to fear.... 

Since the beginning of time, the angelic forces of the High Heavens and the demonic hordes of the Burning Hells have been locked in eternal conflict for the fate of all Creation. That struggle has now spilled over into Sanctuary - the world of men. Determined to win mankind over to their respective causes, the forces of good and evil wage a secret war for mortal souls. This is the tale of the Sin War - the conflict that would forever change the destiny of man. 

For a thousand years, the Sabbat Worlds have been lost to the Imperium, claimed by the dread powers of Chaos. Now, a mighty crusade seeks to return the sector to Imperial rule. And at the forefront of that crusade are Colonel-Commissar Ibram Gaunt and the Tanith First and Only - better known as Gaunt’s Ghosts. Trapped in the grinding trench warfare of Fortis Binary, the Ghosts find themselves drawn into a conspiracy to assassinate the crusade’s leader, Warmaster Macaroth.

The Covenant mission is the most ambitious endeavor in the history of Weyland-Yutani. A ship bound for Origae-6, carrying 2,000 colonists beyond the limits of known space, this is a make-or-break investment for the corporation - and for the future of all mankind. Yet there are those who would die to stop the mission. As the colony ship hovers in Earth orbit, several violent events reveal a deadly conspiracy to sabotage the launch.
