Excession is Iain M. Banks' fourth novel in the Culture series.

Published in 1996, it received tremendous acclaim for its originality. Excession offers detailed insights into the political, cultural and militaristic arenas of the Culture universe, embellishing on previous works.

Of the Culture series, Excession's narrative is unique, focusing more on the interactions among Minds and less on the actions or opinions of humans, the latter all but relegated to spectator status. This approach not only typefies the limited democratic facility allowed humans in The Culture, but further emblemizes the true chain-of-command inherent in the civilization of the protagonists.


The Excession of the title is a perfect black-body sphere that appears mysteriously on the edge of Culture space, appearing to be older than the Universe itself and that resists the attempts of the Culture and technologically equivalent societies (notably the Zetetic Elench) to probe it. The Interesting Times Gang (ITG), an informal group of Minds loosely connected with Special Circumstances, try to manage the Culture's response to the Excession. The Affront, a rapidly expanding race named for its systematic sadism towards subject species and its own females and junior males, also try to exploit the Excession by infiltrating a store of mothballed Culture warships and using them to claim control of the mysterious object.

The Sleeper Service, an Eccentric GSV is instructed to head to the location of the Excession by the ITG. As a condition the Sleeper Service demands that Genar-Hofoen, a human member of Contact, attend it to seek a resolution with his ex-lover who is the final human passenger on the GSV. They had had an intense love-affair and, after a series of sex changes, had each become impregnated by the other until Genar-Hofoen was unfaithful and Dajeil attacked Genar-Hofoen, killing the unborn child. Dajeil then suspended her pregnancy and withdrew from society for 40 years and the Sleeper Service hopes to effect a reconciliation between them.

As the stolen Affront fleet approaches the Excession, the Sleeper Service deploys a fleet of 80,000 remote controlled warships, neutralizing the threat. It transpires that the Affront have been manipulated into their grab for power by members of the ITG who thought it was morally imperative to curb the Affront's cruelty by any means, and intend to use the Affront's theft of Culture warships as an excuse for war. The Excession releases a wave of destructive energy towards the Sleeper Service. In desperation, the Sleeper Service transmits a complete copy of its personality, its "Mindstate", into the Excession, including its knowledge of the conspiracy that has the effect of halting the attack. The Excession then vanishes as mysteriously as it appeared and the brief war with the Affront is halted.

During these events, and after speaking with Genar-Hofoen, Dajeil decides to complete her pregnancy and remain on the Sleeper Service, which sets course for a distant Galaxy. Genar-Hofoen returns to the Affront, having been rewarded by being physically transformed into a member of the Affront species (whose company he finds more stimulating than that of the Culture's people).

The book's epilogue reveals that the Excession is a sentient entity that was acting as a bridge for a procession of beings that travel between universes. It also assesses whether the species and societies it encounters are suitable to be enlightened about some unknown further existence beyond the Universe; as a result of events in the story the Excession concludes that the civilisations it has encountered in this universe are not yet ready for enlightenment. It also takes the name given to it by the Culture – The Excession – as its own.
