Of the five largest mass extinctions of living beings in Earth’s history, only three were caused by natural factors. The remaining two were attempts at colonization and the destruction of life on our planet. I knew this, but I couldn’t imagine that I and my fellow from the elite Corps of Special Operations of the Martian Guard would have to take part in these events. To save my home world, I must defeat the invaders who possess unimaginable technologies. Yes, the journey from the distant past into the familiar world turned out to be far from as easy as I’d expected. But my goal remains the same: to return. And to save my home world from the terrible fate of being “read” by unknown Creators.
