If someone would have told me even a fortnight ago I would have enjoyed a Star Trek novel which focused on the Cardassian race and culture I would have been sceptical but I've learnt from various interviews and reviews that Una McCormack is well respected in creating stories within the Trek universe and really bringing the Cardassian people to the fore. This may just be my thing but it didn't hurt that The Never Ending Sacrifice weaved it's story around a character introduced in the Deep Space Nine tv series (which I rate highly) and the story evolves with the events in the tv show over the next few years playing out as background. This approach added a huge amount of depth to the novel and I suspect anybody reading this novel will be familiar with the tv series and the extra detail the story provides in turn makes you appreciate DS9 even more.
While the novel centers on Rugal Pa'Dar (Featured in the DS9 second season episode "Cardassians" in which as a war orphan adopted by a Bajoran couple it's revealed his "real" father who thought he was dead has returned to claim his son. Behind all this is the devious hand of Gul Dukat and it's this hugely complex culture of political maneuvering and posturing combined with a fierce pride in the culture and society Rugal has to deal with when he returns as a dutiful son of Cardassia. As you would imagine a young man raised on Bajor having seen the atrocities committed by his people will have issues dealing with the Cardassian society and that's the tale we are being told and you will see a culture that isn't as black & white as we first thought and given the chance there are those who are striving for a better and fairer Cardassia unshackled from the repeating cycle of domination, control, and destruction used to maintain the political and military society all have to live under.
The Never Ending Sacrifice is a very enjoyable read which I didn't want to put down and despite not being totally familiar with the Trek universe post DS9 it was very easy to slip into the universe as created by Una's story telling, I can highly recommend the novel for a Star Trek fan or someone looking to dabble into the franchise without getting into one of the long running series or maybe use this as a stepping stone into an ongoing series.
