Zombies of Chronos — Tom Ciolli

Several species from ten thousand years in the future begin to interfere with life in New Athens. Soldiers who perished in a space battle were flash frozen in the void of outer space and begin to appear in present day with some malevolent modifications. A conspiracy to subvert and eliminate Defense Corps., becomes obvious as these zombie soldiers begin appearing in a reanimated form with numerous high tech implants. New strategies need to be developed to defeat the advanced technology used to resurrect the dead and build an army of zombie warriors controlled by a hive mind.
Zach Murphy and his team once again need to rely on time travel, telepathy, the acquisition of future technology, and good old fashioned wit and stealth to survive. The Wolverines have to go from having no knowledge of their attackers, to a place where they control the threat and are able to take decisive action.
