The Excession is what the Culture's social scientists describe as an Outside Context Problem, one which a society cannot foresee and is often fatal.

Meanwhile a rapidly-expanding race, which the Culture calls the Affront (because of its systematic sadism towards subject species and its own females and junior males, despite being relatively advanced), tries to exploit the Excession by infiltrating a store of mothballed Culture warships and using them to claim control of the mysterious object.

, the Culture's covert operations organization. The name of Sleeper Service is thus double-pronged—it is a Sleeper Service to human beings in Storage, and a Sleeper Service within SC, as it has produced a massive war-fleet during the 40-year period it has spent behaving as an Eccentric. It prepares to deploy this fleet during transit to the Excession.

But Sleeper Service has an unresolved issue. Until a few decades previously, the ship operated under another name as a normal GSV, providing a habitat for a vast number of Culture citizens. Two of its passengers, Dajeil and Genar-Hofoen, had had an intense love-affair which ended badly when Genar-Hofoen was unfaithful and a pregnant Dajeil tried to kill Genar-Hofoen, but only succeeded in the feticide of the child with which Genar-Hofoen was pregnant. After the break-up, Dajeil froze her pregnancy and subsequently remained in a state of intense depression for 40 years, and the ship changed its name to Sleeper Service and started acting as an Eccentric. It carried only one conscious humanoid passenger, Dajeil, and spent much of its attention trying to talk her out of her depression, for which it considered itself partly responsible.

As a result, when the Culture asks Sleeper Service to help in dealing with the threat of war, the ship demands that in return Genar-Hofoen must be handed over to it. Genar-Hofoen is lured to Sleeper Service on a pretext, and only later told that he is there to work with Dajeil to help her recover from her psychological trauma.

Sleeper Service then unloads the passengers who had been part of its historical tableaux. Having spent much of its Eccentric decades converting a large percentage of the mass of the tableaux' scenery into engines, it easily outruns the very fast ship which other elements of the Culture had asked to keep watch on it. Once it is beyond the watching ship's sensor range, Sleeper Service changes course and heads towards the Excession. When it arrives it becomes apparent it has previously converted the rest of its spare mass into a vast fleet of remote-controlled warships numbering in the area of 80,000 units. The Excession, in response to the Sleeper charging at it, then triggers a multi-light-year Gridfire wave which threatens to obliterate it and its entire fleet, along with the accompanying Grey Area

. Only its Mindstate, transmitted right at the Excession, saves it by convincing the Excession to halt its attack. The Minds controlling the ships which the Affront stole from the "mothball" find themselves outnumbered more than 130:1, and refuse to help the Affront. The Affront fleet's commander and the Culture ship which led the conspiracy commit suicide. A prolonged war is thus averted. At the same time the Excession disappears as mysteriously as it arrived.

Meanwhile, the rush of events, combined with a conversation with Genar-Hofoen, results in Dajeil moving out of her depression and completing her pregnancy. 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 which is currently acting as a bridge for a procession of even higher beings which 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 our universe are not ready for this enlightenment and moves on so that it will not cause any further disturbance, hence its disappearance at the end of the book. It also takes the name given to it by the Culture – Excession – as its own.

Outside Context Problem

This novel is about how the Culture deals with an Outside Context Problem (OCP), the kind of problem "most civilisations would encounter just once, and which they tended to encounter rather in the same way a sentence encountered a full stop."

This is a problem that is "outside the context" as it is generally not considered until it occurs, and the capacity to actually conceive of or consider the OCP in the first place may not be possible or very limited (i.e., the majority of the group's population may not have the knowledge or ability to realize that the OCP can arise, or assume it is extremely unlikely). An example of OCP is an event in which a civilization does not consider the possibility that a much more technologically

Banks' view of the Culture

The book, more than any of the other Culture novels, focuses on the Culture's Minds

, Banks said about the book:
Also significant within the Culture novel cycle is that the book shows a number of Minds acting in a decidedly non-benevolent way, somewhat qualifying the godlike non-corruptibility and benevolence they are ascribed in other Culture novels. Banks himself has described the actions of some of the Minds in the novel as akin to "barbarian kings presented with the promise of gold in the hills".

Reviews
