No Man's Land Series by Griffin Hayes

This is the third and final installment of the Hive series. With Sotercity in ruins, Azina and the others must race to stop Skuld from destroying the capital and taking control of the ten territories. But soon a secret will emerge. Hidden for nearly two centuries, it may spell doom for not only Azina and her friends, but for the entire world.

It's The Keepers of Knowledge who run things, as they have for the last two centuries, working to recover any technology that might have survived humanity's fall. So when The Keepers hire Azina and her eclectic crew of hardened veterans to find four lost Prospectors, it sounds like easy money... moreThere aren't many opportunities for women in Azina's post-apocalyptic, zombie ravaged world; least of all mercenary leader.

So when The Keepers hire Azina and her eclectic crew of hardened veterans to find four lost Prospectors, it sounds like easy money. The search leads the group to a crumbling underground city. But what looks like just another ruin from a bygone era isn't nearly as deserted as it appears. A horde of bloodthirsty Zees are stirring from a long slumber, and these zombies aren't like anything in the history books. They share a hive mind. When one sees you, they all see you. And worse than that ... something may be controlling them. less
