Query: Esign Ro and all the irregular regulars on DS9

The new guy on the cover named Vaughn is chief of security aboard the station. With Odo back on his homeworld someone has to fill his shoes. This officer has had a long and varied career in the fleet. Col. Kira is now in charge of the station. We get to see Nog as a Lt. on the Defiant. The place has changed a bit. Quark is still fixing his Dabo tables.All in all it's a story that takes place after the Dominion War but it's still a good series. If you are a fan go out and buy this one.
