The year is 2098. Humanity is no more.
Earth is a ravaged, radioactive wasteland.
On Mars, a small group of synthetic humanoids survive—their memories of the apocalypse wiped, seeking to understand their role in the fall of humanity.
Until Sol-5 receives a message. A message from a possible human survivor, and a plea to go to Earth to find her.
But what he finds there will change everything.
The humans were wiped out for a reason.
Homo Machina is the new post-apocalyptic thriller from the pen of award-winning author PA Vasey [Harbinger, Trinity Trilogy].
