ARKLIGHT Regulus is the exciting and dramatic conclusion of the ARKLIGHT Ancient Alien Adventure Trilogy. The global war rages as Dr. Tegan Strong-Locke and her allies struggle to stop the alien Etu Inu Idimmu from decimating the human race. Human resistance is strong, but willpower and the efforts of a united world military aren't enough to stop the Idimmu and their genetically engineered killing machines, the Xunta. As the Idimmu and the Xunta continue their relentless worldwide attacks, Tegan and an alien ally, the Igigi, work feverishly to produce and launch Deep Sky, a bioweapon that offers humanity the best hope against the onslaught. But Deep Sky alone may not be enough to provide salvation. New Xunta have been released and they are faster, more cunning, and they can swim. The underwater cities and outposts are now at risk. As Tegan and her unborn child, Kyla, grow stronger in Arklight energy, they learn that the power they control may offer another path to peace. It will require them to face the Monan, the supreme ruler of the Idimmu. The risks are high and there's no guarantee their confrontation will end the slaughter. But they have no choice. They must try before it's too late.
