Star Trek: Dominion War
The Dominion War is a series of four novels set at the beginning of the Dominion War. Books 1 and 3 focus on the crew of the USS Enterprise-E, while books 2 and 4 are novelizations of the seven episode arc that began with DS9: “Call to Arms” and ended with DS9: “Sacrifice of Angels”.
An anthology entitled Tales of the Dominion War, released later, collected a series of short stories based on the same conflict.
