Klingon Empire: A Burning House by Keith deCandido

Another excellent offering from deCandido. Any Klingon loving fans will want to read this series, although the quality of the writing varies wildly. Old characters, new characters, and Klingon Opera. If you want to know what happened to the Klingons in the Carraya system,. here is the answer.

Worlds on DS9; Ferenginar, the Dominion

The novellas take a closer look at the societies we see on Deep Space 9 while following the lives of select characters post series.
Satisfaction Not Guaranteed takes place mostly on Fereniginar, where Grand Nagus Rom must deal with Brunt, his brother, and the birth of his second child.

Olympius Descending concerns why the Founders sent out the 100, and where their society is going post Dominion war.
Excellent, must reads for any DS9 fan.
