" "Transition" is typical of Banks' more recent (and lazier) science fiction- multiple character perspectives, stories within stories, a deus ex machina that gets pulled out towards the end to sort of tie things up without actually resolving very many of the plot points - but it's not his best science fiction by a long shot.The tale revolves around a mysterious organization calling itself The Concern, whose adepts can "transition" or jump from reality to reality in the many-dimensional multiverse, occupying bodies from which they temporarily displace the owner, in order to carry out political, social and plain murderous manipulation of that reality. A particular member of the Concern is trying to take control of the whole apparatus for her own ends and eliminate everyone who would oppose this, but a resistance is in place and has plans for thwarting her.Banks does a workmanlike job of building out his key characters, and in true Banksian form drops enough ambiguous references from several of the various narrators that one is never quite sure until the end whether some of the key characters are in fact the same person, only in different realities or times, but the novel is undercut by Banks' increasing tendency to lecture his readers, through the narrative, on the shortcomings of limited-liability capitalism, authoritarian government in the name of security, and religion in general.
