But now the Anguilar know where that home is...and it's only a matter of time before they set their sights on Earth, intent on conquest and enslavement. Charlie doesn't have enough troops or supplies to stop them. And there's only one place he can get them. The one place the Anguilar are intent on conquering. Charlie has to go back to Earth...and hope, after all this time, that it's still... The Home of the Brave.
