On the eve of Bajor's formal entry into the Federation, First Minister Shakaar was assassinated, derailing the induction and plunging the planet and station "Deep Space 9(TM) " into chaos. Investigation into the murder revealed the presence of a parasitic conspiracy threatening not only Bajor's future with the Federation, but the very survival of both.

They were created to be killing machines. Highly intelligent, resourceful, and deceptively complex, the Jem'Hadar are a species engineered for war and programmed at the genetic level for one purpose: to fight until death as soldiers of the sprawling stellar empire known as the Dominion. No Jem'Hadar has ever lived thirty years, and not even their masters, the shape-shifting Founders, know what such a creature is capable of becoming were it to be freed of its servitude. One Founder, however, has dared to wonder. Appointed by Odo himself to learn peaceful coexistence aboard Deep Space 9 â„¢, Taran'atar, an Honored Elder among the Jem'Hadar, had for months been a staunch, if conflicted, ally to the crew of the station, ever struggling to understand the mission on which he was sent . . . until something went horrifically wrong. Consumed by self-doubt and an ever-growing rage, Taran'atar has lashed out against those he was sworn to aid. While Captain Kira Nerys and Lieutenant Ro Laren both lie near death aboard DS9, their assailant has taken a hostage and fled into Cardassian space, pursued by Commander Elias Vaughn on the U.S.S. Defiant. But as the hunt unfolds, Taran'atar's true objective becomes increasingly less certain, as the rogue Jem'Hadar leads the Defiant to a discovery even more shocking than his crime.

In our universe, a Cardassian sleeper agent—Iliana Ghemor—was once surgically altered to resemble and replace resistance fighter Kira Nerys, future Starfleet captain and hero of the planet Bajor's liberation. That plan never reached fruition, and the fate of the agent remained unknown...until now.Robbed of the past sixteen years, Iliana Ghemor is back with a vengeance. Over a decade and a half of imprisonment and abuse by her former masters has brought her to the brink of madness, sustained only by the twisted belief that she is, in fact, the real Kira Nerys. She has already made one near-successful attempt on the real Kira's life, but instead of assuming the identity of the woman she was intended to replace, Ghemor has set her sights on the most unexpected target of all: Kira's other double, the malicious Intendent, Bajor's iron-fisted ruler in the alternate reality commonly known as the "Mirror Universe." But far more is unfolding in the Mirror Universe than Ghemor realizes, and the heroes of Deep Space Nine somehow must stop the false Kira without derailing the delicate flow of history that must unfold if both universes, and countless others, are to survive. Parallel stories set in both universes reflect and build upon each other in this Two-in-One "Flip Book," the continuation of both the ongoing DS9 saga as well as the Mirror Universe line of books.

Continuing the events from Star Trek: Fearful Symmetry, a new novel in the ongoing Deep Space Nine series set after the end of the critically acclaimed television series. Captain Kira’s lookalike, Iliana Ghemor, dreams of fulfilling a prophecy that will mark her as the one true Emissary of the mirror universe—a messianic figure who will lead her followers into a war that could trigger the cleansing of countless alternate Kiras in countless parallel realities. But the stakes are higher than anyone imagines, for the pull of destiny tugs at other souls who are swept into the vortex of the Prophets, remote and timeless beings who have set these events in motion. Yet the outcome of this struggle for the fate of one universe will ripple across many others, giving shape to a future that will prove to be greatest trial yet for the heroes of station Deep Space 9.
