Alex Through the Looking-Glass, by Alex Bellos
I’ve read Alex Bellos before and quite liked the first one. This one is good too, barring the first chapter which feels more like a chapter on numerology/favourite numbers etc.
Olympos, by Dan Simmons
The sequel to Ilium and quite enjoyable, although massive. Somehow the author makes it all work in a way that is quite satisfying.
The Dispossessed, by Ursula K. Le Guin
My first Le Guin. A scientist from an anarchist moon colony escapes to the mother planet and is faced with a clash of ideas. I wasn’t too sure what to expect from this but was pretty happy with how nuanced the cultures were.
