Book 3 of 3 in the Star Trek: Deep Space Nine miniseries entitled Millennium.
"As predicted in ancient Bajoran texts, the Celestial Temple has been restored, ending normal space-time existence for all except Captain Benjamin Sisko and those trapped on the Starship Defiant and the Klingon warship Boreth. But as apocalyptic war rages between the Prophets and the Pah-wraiths, one last chance for survival beckons—a return to Deep Space 9."
Note: Elim Garak plays a large role.
