The soul key - Olivia Woods

Cardassian agent Ileana Ghemor, who was once surgically alterered to resemble and replace the Bajoran Kira Nerys, 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 open the way to cleansing the multiverse of countless alternate Kiras in countless parallel realities. But the stakes are higher than anyone imagines, for alongside Ghemor, the pull of destiny tugs at other souls who are swept into the vortex of the Prophets, the remote and timeless beings who have set these events in motion. 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 the greatest trial yet for the heroes of space station Deep Space 9.
