It has been four years since the Brood War Conflict ended within the ravaged Koprulu Sector. In that time, Sarah Kerrigan, the self-styled Queen of Blades, has become the undisputed ruler of the zerg Swarm – and the most powerful entity in the galaxy. Emperor Arcturus Mengsk, Kerrigan’s sworn enemy, has rebuilt much of his Terran Dominion and consolidated a new military force despite the ever-present threat of the zerg.

Mengsk, with the aid of his newly appointed advisor – General Horace Warfield – has begun a clandestine research project code-named Project: Shadow Blade. This covert program utilizes a rare and deadly form of gas known as terrazine to alter the genetic makeup of the Dominion’s psychic Ghost operatives. These Ghosts are transformed into terrifying Spectres – shadowy superhuman beings bent on executing the will of their true master.

In this boiling cauldron of strife and subversion, the young Ghost known as Nova has come of age. Having received years of intensive physical and psychic training, Nova has become the Dominion’s most lethal and promising Ghost in years. Utilizing a combination of pure physical aptitude, innate psychic power, and advanced technology, Nova can infiltrate any situation and strike without being seen or heard. Like a phantom in the shadows, she exists only as a myth to the enemies of the Dominion she serves.

Yet, despite her skill and cunning, Nova is about to uncover a conspiracy that will force her to question her deepest loyalties as well as her own identity. Ensnared in a bitter struggle between the Dominion and the rebel Koprulu Liberation Front, Nova will embark upon a perilous mission to uncover the frightening truth behind Project: Shadow Blade. Now, the dark path that Nova must tread threatens to not only change her forever – but upset the very balance of the galaxy.
