Twenty Million Years - Paul D. Escudero - Bog

It is twenty million years in the future. Although a calamity long ago destroyed Earth, somehow archeologists have just unearthed a Moscow subway train full of passengers with their print media from 2022 perfectly preserved. Now the archeologists must answer a complex question: Did the Jupitorians annihilate the world as they have all been told by the Cobasta Aliens, or did the world self-destruct?
While the archeologists travel to Mars and uncover more truths, another alien entity is planning to conquer the galaxy. They have one empire to crush before their despot leader can proclaim himself the emperor of over half of the Milky Way. Meanwhile Chirak, a robot living in a stolen human's body, is on a determined mission to warn the Cobasta and others that they are being targeted for destruction. As a showdown begins, Chirak becomes entwined in intrigue and espionage as he transforms into one of the most advanced spies in the galaxy with a new mission to take down its menacing empire.
In this gripping science fiction adventure set twenty million years in the future, archeologists and a humanoid robot work to uncover truths from 2022 in order to understand the current galaxy.
