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.
