The Humans by Matt Haig takes a fun, irreverent look at the human species, our appearances and way of life. The novel revolves around the narration of an alien species called the Vonnadorians, in the form of a report to his superiors.
The author did not tell the readers what the alien looked like, but from the alien's horrified reporting of humans, one can allude that Vonnadorians most likely resemble a round ball with huge eyes. "Their faces alone contain all manner of curiosities. A primitive external auditory organs known as ears, tiny eyes and unfathomably pointless eyebrows." It went on to describe the "primitivenesss" of having external limbs, and the unfathomableness of the law requiring the human species to wear odd things called clothes.
This description of humans resonated with me as I had, between 2008 and 2010, written another blog from the perspective of my cats. I had wondered what my cats thought of us changing our clothes all the time, our activities, our going-in and going-out of the house and coming home with bags of groceries or new household items. So, from my cats' point of view, we were constantly changing our skins, we sometimes hanged our skins on coat hooks, put them into a square looking contraption that washed and tumbled-dried our skins and we went out to hunt for food at fixed hours daily, but were only successful at weekends.
But I digressed. Back to the novel, the nameless alien was placed on earth to take the place of a brilliant mathematical professor, Andrew Martin. It was hinted that the said professor was abducted and killed by the Vonnadorians for a breakthrough mathematical discovery that would threaten the universe.
The narrator alien's job was to find out who Andrew Martin had revealed the mathematical evidence to, assassinate those who knew, and destroy the evidence.
