Omega Cometh [EPUB ebook] 

What would you do if you found out Earth’s annihilation was a decade away?

Riveting Thrill-ride!

The three Superpowers are warring for resources when in the mist of the chaos, a washed-up, old- school astronomer discovers Earth is doomed. Events set in motion billions of years before the Earth was even formed, send an asteroid barreling down on the Earth at 22, 000 miles per hour.

Espionage, intrigue, and distrust bring the Superpowers into conflict that threatens to stop the one effort that has a chance to save humanity!

Is Omega! The End?
