The Gathering — Ronald Wintrick

Book Two of the Antz series finds mankind being swept from his own worlds, put to flight and scattered like cosmic dust. The Fleet has been routed. They can't stand toe to toe with the enemy. The only hope is that mankind can hold her worlds, but they will have to be held from the ground, and they were on their own. It has been a long time since man has been hunted by anything other than his own fellow men, but the instincts were still there.
