Sectors Twenty-Six & Twenty-Seven (2014)

From publisher blurb:

The exploration of “Unexplored Space” continues with Sectors 26 & 27. You’ll find a few colonies in this tome, but you’ll also find lots of planets waiting to be explored, and planets that were once colonized, but no longer are.

There are more machine culture colonies that have been abandoned; some of which may have treasures beyond imagination left on them. Abandoned and destroyed colonies of an ancient culture known as the Glikth are here to be explored. Plus there are the usual mysteries that can be found where no one has been in centuries.
