I decided I need to read more Science Fiction so I started a series that has long been on my to read list, Consider Phlebas by Iain M. Banks
I am keen to know what you think of it, as I am currently rereading the Wasp Factory which is a great book by him also.
Consider Phlebas is the start of Banks' "Culture", which ranges from "not enough Culture" to "amazingly remarkable". Banks is one of the big eighties wave of UK sci-fi authors who redefined the genre with seminal works of giant space opera that somehow still manages to have great characters at the centre of the story. The books don't have to be read in order, as although they occupy the same fictional universe, the stories don't follow on from each other and only occasionally does a known character (fleetingly) show up more than once.
The Culture are a hugely advanced, space-faring AI run society where anything is possible for the human-like creatures that are a part of it. Contact are the diplomatic arm, and Special Circumstances are their shadowy sub-section that deals in espionage, which is often where the bleeding edge of the Culture is portrayed in Banks' books. My personal favourites are "The Player of Games" and "Excession", but they are all good books played out against the background of the Culture. The ship names and the way they talk to each other are a favourite of mine.
Consider Phelbas takes place during a war the Culture are fighting with the Iridians, and concerns a Shaper spy (who can biologically change his body) working on the enemy side to try and reach a crashed ship Mind/AI before the Culture can retrieve it. A Special Circumstances agent is working against him, but for the most part the story follows the Shaper agent. Like most of the Culture books, the Culture is more a backdrop than the main story, which allows Banks to concentrate on the characters, rather than getting lost in too much of the techno-porn that other authors can fall into. There's lots of world building, lots of sci-fi tech, lots of action, a portrait of the alien society Special Circumstances are operating in, but with Banks the core is always the character.
Banks' other non-Culture sci-fi books are also worth reading, but they don't take place in the Culture universe. They are all books that I've read several time over, and each time I manage to find new things in them. Banks' was a bit of a sci-fi story-telling genius, and when the news was released that he was dying at the relatively young age of 59, I lamented all the stories he was never going to be able to tell had he lived another 20-30 years.
There are none of his sci-fi books (monikered as Iain M Banks, rather than Iain Banks for his non-scifi books) that aren't worth reading more than once. Iain Banks' sci-fi novels are pretty much required reading for anyone into the genre, and you can see where so many other authors have been inspired by his work.
Once you've finished Banks' work, you can draw a hereditary line straight to the more kinetic and action packed books of Neal Asher's Polity universe.
