The Republic of Mars: Fifth Era (Book 1‪)‬

1942.
The city of Los Angeles is facing highly advanced, unknown forces. Its defenses try to shoot down the mysterious vessels, but fail. Even though the unknown beings change their minds and return to the ocean waters, the government plays down the incident. They don’t want to admit failure.
2026.
Asher is a computer genius who works for the government in Washington. In a repeat of the 1942 incident, a city-sized UFO suddenly emerges from the Pacific Ocean and flies towards Los Angeles. Fighter jets are scrambled to shoot it down, but it evades them. It continues on to Las Vegas, where it drops its speed once again.
Panic is everywhere. It’s possibly an alien invasion.
The city-sized UFO keeps moving eastward and arrives in Washington, D.C. But while the Joint Chiefs Chairman is planning to use lasers to shoot down the aliens, Asher thinks the UFO may actually be friendly. He suggests diplomacy.
The US President is fearful and self-absorbed, but knows that they are militarily unable to defend against them. Negotiation is their only option. As a gesture they walk onto the White House’s South Lawn, ready to meet whatever fate awaits them.
The real danger arrives unannounced. They talk of friendship and aid, but that’s not true. Mankind has reached a crossroads.
