Aurora was a very challenging read for me - hard SF in which the science was (for me) HARD. Constant trips to Wiki to get enough of a gist of phrases like "kolmogorov complexity" and "Winograd schema" to try to get enough of an idea of what they meant to be able to follow the story. Which was in some ways apt, because "science is hard, space is HARD" was really a big part of the story.

Now back to Urdu poetry and Le Petit Prince both of which will tax my brain less than the maths of Aurora, that's for sure!
