Axpherial: Demolition (E-Book)

Book summary: 

After saving Earth and Axpherial, Kam and Maxine believed they'd restored peace. However, their celebration is short-lived when they discover that their heroic efforts only postponed a cataclysmic invasion. Millions lost their lives, and now, millions more are at the mercy of the Herloids—a supposedly extinct race with a mastery of science and technology.

As Kam and his friends confront this resurgent threat, they quickly realize that the Herloids have evolved, becoming more powerful and destructive than ever before. Yet, lurking in the shadows is an even greater menace, one with sinister intentions and boundless power.
