I just finished reading the audiobook. Overall I really liked it, but that's partially colored by the fact that I'm a fan of the Cyberpunk universe.
A couple, non-spoiler comments regarding the book.
- It's not clear when this takes place in the timeline. It could be before, after, or during the Cyberpunk 2077 game. I'm not sure that it matters.
- The way the book jumps between characters can be confusing. Cherami Leigh does do voices for the different characters but they are not very distinct. When the perspective jumps to a new character, it can take a moment to realize it.
- Since there is no single protagonist, you don't really form a connection with any particular character. They each have their own reasons and motivations but none of them really stand out.
- There are references to some minor people and places in the game. While the fanservice is cool, it does make Night City feel a little small. What are the odds that the characters of the book are in the same places, talking to the same people as the game? Luckily it doesn't happen all the time.
- I think the connection to one or more storylines in the game is possible but tenuous. There are similarities but nothing direct.
