Warrior's Wrath. The Warrior Chronicles, #4

The living embodiment of war, Cort Addison is a twenty-first century warrior molding twenty-fourth century humanity into the spear that will protect the Ares Federation. When the Tapon, harboring a millennia-old grudge against Cort's alien allies, use force and subterfuge to take back their ancient homeworld, they cannot be prepared for the retribution Cort brings against their species. Any hope of peace is crushed when Cort learns a recently vanquished species has escaped their prison world and is swarming through Ares Space.
Cort must again find a way to save his family and his allies from ancient enemies hell-bent on revenge.?
