I've read all of Gibson's books, but I found Agency hard to finish.

The book has two parallel story-lines, and very short chapters which makes it a very disjointed read.

The characters were also very flat. For the last quarter of the book, the main character's dialog is almost all short questions and other characters explaining things to her. e.g.

<paragraph explanation> "why's that?" <paragraph explanation> "oh really?" <paragraph explanation> etc.

Unappealing characters. Boring plots. Whole novels based on a couple of ideas. It feels like 90% filler.
