Books finished in April:
(Warning: reviews are unpolished and quickly written.)

The Affinities (2015) by Robert Charles Wilson. Near future science fiction. New methods enable mapping people into “affinities”-collections of like minds maximizing the potential for cooperation. These groups of course become rivals. Recommended.

Julian Comstock: A Story of 22nd-Century America (2009) by Robert Charles Wilson. Did not finish. It feels like Wilson wanted to write a clichéd, predictable, traditional fairytale/adventure in an unlikely post-apokalyptic setting (though not really apokalyptic, the world has simply come down from previous, excessive consumption fuelled by oil) as some kind of experiment, but I just got bored. Not recommended.

This Is Your Brain on Sports: The Science of Underdogs, the Value of Rivalry, and What We Can Learn from the T-Shirt Cannon (2016) by L. Jon Wertheim. Mix of solid research and more speculative stuff about various phenomena related to sports. Easy to follow, and easy to forget. Ok.

Diaspora: A Novel (1997) by Greg Egan. Forms of post-humanism. I enjoyed the parts that I could follow, which were not too many, due in large part to a crappy audiobook edition.

Ratings and old books are in the library.
