The Humans is a book I could reread once a year. This is a bold statement, I know, especially since the premise is an alien assassin has been sent to Earth to kill a mathematician and erase all evidence of a potentially dangerous theorem. The story and our narrator, the alien acclimating to human life, become much more. I appreciate a narrator that confides in the reader and becomes a fully developed voice in your mind’s ear. Matt Haig’s alien fills that role beautifully.
