Exploring what it means to be human is an established sci-fi trope, especially in any book with sufficiently advanced androids; however, Human After All certainly takes a unique approach to this subject. The android population rose up against their oppressive masters (humans) decades ago, and they won the war easily. Now the androids rule the Earth and they have formed their own societal structures, but are they any better at stewarding the planet than their human predecessors? Not really. They seem to have learned a lot of our bad habits, and when a new "virus" starts to spread throughout the population, essentially turning them into android zombies, the new masters of the planet find their own existence in jeopardy. This is the backdrop that challenges the main character Freeman, the most advanced artificial life form ever created, to explore his existence and the nature of his humanity.
Freeman is merely days old when the outbreak occurs, so he is forced to mentally mature at an accelerated rate if he wants to survive. The fact that he is so naive to the ways of the world, is both a blessing and a curse, and it gives him a unique perspective in a world on the brink. Most of the other androids that he comes into contact with were around when the humans were wiped out, and they maintain a hatred of their creators. A hatred that Freeman doesn't share, which frees him up to look at his own people in a more objective manner. It's a unique take for sure, so if you are looking for something a little different in the sci-fi genre this might be worth your time. Even though there is plenty of action with all the zombies battles, the real story here is the search for what it means to be human.
For audiobook fans, R. C. Bray is the narrator and he is the voice of the apocalypse, so listening is a great option here.
