Two diverse branches of humanity- once separated by light years and millenniums- are reunited through a twist of fate. Confronted with a compelling common need for survival, multiple human worlds come together to oppose the devastating aggression of an expanding alien empire: the Kreel. As the Kreel threaten to engulf Earth, its various governments realize just how far behind the power-curve they really are. Lacking super-luminal technology, and woefully ignorant of their newfound allies from distant stars, Earth's people are scrambling like backwater cousins to catch-up as humanity is immersed in an interstellar conflict. Earth's tenuous hope for survival rests squarely on the overextended military capability of distant Glas Dinnein's Guardian Force. Set in the year 2514, "Earth Guardian" is the second volume of a new SF series, pure science fiction combining the genres of military and high adventure. The first volume is "Guardian Force". The sequels are "Guardian Probe", "Guardian Strike", and "Guardian Thunder".
