The DS9 Relaunch was a series of books set on DS9 after the end of the series. They introduced some new characters (some newer than others) including Lt. Ro Laren (from TNG) as Security Chief, Commander Elias Vaughn as first officer, Andorian Lt. ch'Thane as science officer, and tame Jem'Hadar Taran'atar who was sent by Odo to serve Kira (long story...).
In all, I found the books enjoyable. If you like Trek fiction, I highly recommend them.
