Walkaway by Cory Doctorow. My first Doctorow, and I am not sure I will do any more. A hash of steampunk, cyberpunk, biohacking, post-gender, libertarian themes all jammed into a stew, and there just isn’t much story or character in there.
Less by Andrew Sean Greer. Contrast with above, a great character finding himself in the middle part of his life. Informed by the generations before and after him as they deal with their own crises.
Babel by Gaston Dorren. A look at each of the top 20 most used languages in the world. And a lot of cultural insight along the way. Very good.
