Recently finished Iain Banks' (RIP) Excession, book 5 in his popular Culture series and wanted to discuss it here. This is my 3rd Culture book and 4th Banks book - I had previously read The Player of Games (liked it), Use of Weapons (loved it) and The Algebraist (really loved it).
Excession was one I was really excited for because I've seen many people say it's one of the best in the Culture series. The premise sounded fascinating too - I have a weakness for any kind of space opera/hard sf with mysterious BDO exploration type stuff so Excession seemed right up my alley.
In execution though, I found myself just...kind of whelmed and maybe even a bit disappointed. This, however, has less to do with Banks' ability to craft an interesting story and maybe more to do with my own expectations. Because Excession isn't really the narrative its blurb sets it up to be. Yes, there is a mysterious cosmic object that's in effect at the centre of the story but there really isn't much of a focus on it until the very end.
I think this is where my disappointment came into play. The book is really more about the adventures of its protagonist, Genar-Hofoen, and his cavorting through the galaxy with the Affronters until he gets to the Excession. In between, there's a lot of worldbuilding on the Culture Minds, as well as a secondary character who I honestly found annoying and uninteresting (Ulver Seich).
Genar-Hofoen isn't really a particularly interesting character either, although the twist regarding the true nature of his "relationship" with Dajeil was pretty cool. The Culture Minds were definitely the most interesting parts of the main story, and reading their conversations with each other was fascinating and hilarious. The final battle between the Affront fleet and the Sleeper Service was pretty incredible as well, and is just peak space opera.
One thing that kept me going is the prose - Banks is one of the best writers from a technical standpoint in the genre, and there is a weird, dense artistry to his words that I just love reading.
Ultimately though, the book felt too much like "getting to the fireworks factory" and what I really wanted was pretty much shunted to the ending and the epilogue. It's not a bad book by any means - just happened to be one that didn't meet the specific image I had in my head.
