Dark Passions: Book 2 of 2 (Star Trek)

Intendant Kira, now Overseer for the entire Klingon-Cardassian Alliance, has entered into a dangerous liaison with Annika Hansen, unaware that Hansen is actually an agent of the Obsidian Order who has orders to kill Kira when the time is right. But her treacherous alliance is not the only danger the Intendant faces. Both Deanna Troi, the power-hungry consort of Regent Worf, and B'Elanna Torres, the half-human Intendant of the Sol System, are threatened by Kira's unquenchable ambition, and would be glad to see her deposed -- or worse. As four powerful women scheme for control of the Alliance, who will survive? And who will claim the ultimate prize?
