Lost Fleet #6
A good wrap up to the Lost Fleet series.
Geary takes the fleet home, then turns around and hits the syndics so hard that they capitulate, while starting to deal with the alien threat. The getting home arc is over.
There is enough mystery about the aliens that I can easily foresee 4-6 more books about the adventures in dealing with them. If so, I’d hope Campbell uses another character than Geary. The poor guy finally gets together with the other captain, and he needs a break.
