I'm about to start reading this trilogy, and while I've had Book 2 for a few years, I've only recently acquired Books 1 & 3. The write-up on the book seems pretty interesting: the back story of Kai Winn during the Cardassian Occupation. Were any of the back ground details of Winn from this book used in the Terok Nor trilogy from a few years back, since, while Rebels does have framing sequences from the later parts of DS9, the two trilogies appear to tell stories from the same era? Here's the back cover copy from Memory Beta: When Captain Sisko leads the Defiant on a dangerous mission into the Gamma Quadrant to liberate a conquered world, the Bajoran government insists that Kai Winn, the Federation's longtime nemesis, assume complete control of the space station. Left behind by Sisko, Major Kira expects the worst from the Kai's new regime, but even she is caught by surprise when a fleet of alien warships attack Deep Space Nine!
