There aren't many opportunities for women in Azina's post-apocalyptic, zombie ravaged world; least of all mercenary leader. Not that being told no ever stopped her before. 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. 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.
