The Star Trek: Deep Space Nine series was different from many other series in that storylines continued over several episodes. While this allowed the story to be expanded into much greater detail, it also meant that multiple plotlines were often simultaneously followed. While this is acceptable and even sensible in a series, it can be a problem in a book. In this case it is a problem.
After great effort, a peace conference has been scheduled between the Cardassians, the Federation, the Maquis group of guerrilla fighters and the Valtusians. Just getting these sides to a conference is a major achievement and Commander Cisco and the officers of Deep Space Nine (DS9) are having great difficulties in managing all of the security problems. A Bajoran group is also on DS9 and is staging major protests. It is their contention that Gul Mekkar, the leader of the Cardassian delegation, is the perpetrator of war crimes during the Carassian occupation of Bajor.
In the second major plotline, Odo, Worf and Kira are on an undercover mission into Dominion controlled space. They are to make contact with a man who supposedly has information on the drug that the Founders use to control the Jem'Hadar warriors. This mission takes them deep into Dominion territory and they ultimately end up stowing away on a Dominion ship. Since Quark, Bashir and O'Brien are also major characters, there are aspects of the story that involve their actions.
The two major plotlines are just too much for one book and the events where Kira and Worf stowaway on the Dominion ships are absurd. As other episodes have demonstrated, the ubiquitous computer involvement in the running of a ship would mean that an intruder aboard a ship would be easily and immediately detected. This would have been a better story if the peace conference had been the only major theme and the background and context more thoroughly explored. A reader unfamiliar with the series would be left puzzled by some of the references.
