The Second Da-Nah War - Jay Morris - Bog

The Da-Nah are an ancient, colonial, space faring race. In thirty thousand years they never failed, not once. Then they came here, to Earth. To their horror, the Da-Nah learned just how vicious mankind could be. Now a little more than a century has passed and the Da-Nah are coming back, not to colonize, but to destroy the treacherous humans and set reality to rights.
