The futuristic setting is somewhat dystopian, but not enough to be scary. We don't see too much of the outside world, being more concerned with the robots and their adventures, but what we do see is not significantly different than reality. It's only when we see Cog's world that things seem definitely like science fiction. Although, with the companion robots they have in Japan, is it that far fetched?
Van Eekhout does great middle grade science fiction books, including Voyage of the Dogs, The Boy at the End of the World (2011), and Kid vs. Squid (2010). Readers who like robots will read about Cog and wonder what it would be like if Siri or Alexa would come to life in their house!
