Vinctalin Legacy: 0.0015%, Book 10 Alien [EPUB ebook] 

Having fought off many Vinctalin attacks, vanquished them in their own domains, ousted the Veekerens from fraudulent power, and constructed a full and comprehensive Planetary Defence System, the United Citizens of Earth are ready to make plans for the future. They are barely into devising their outline manifestos ready for the very first post-invasion elections, when disaster strikes. Astonishing revelations reveal one species of beings as more alien to Earth Humans than the grey beasts, while Alex encounters a new race of Vinctalin best described as halfway to human, who seem to proffer friendship.
