''Transition'' is a novel by Creator/IainBanks, first published in 2009.

It is based on the premise that a virtually infinite [[TheMultiverse number of parallel dimensions]] do indeed exist. Set between the dismantling of the Berlin Wall and the destruction of the Twin Towers, Transition centres on a shadowy organisation called [[AncientConspiracy 'The Concern']] whose members can transport their consciousness [[BodySnatcher into the bodies of unsuspecting people]] in other dimensions by ingesting a drug called [[AppliedPhlebotinum Septus]] and thus meddle with the socio-political development of other Earths.

!!This book provides examples of:

* AncientConspiracy
* BodySnatcher & BodySurf
* {{Cloudcuckoolander}}: Bisquitine, of course.
* EvenEvilHasStandards:
-->'''The Philospher''': I do draw the line at children. Some of my colleagues will happily oblige when a child must be tortured to force a parent to talk, but I think this is both morally objectionable and suspect in principle."
* GoodPeopleHaveGoodSex
* [[spoiler: FirstContact: Madame d'O's goal is to avoid this]]
* JackBauerInterrogationTechnique
* [[spoiler: KarmicDeath: And how!]]
* KnightTemplar: several, e.g. Madame d'O
* TheMasquerade: Depending on wether you're living in an open or in a closed world a Marsquerade will or will not be in place
* TheMultiverse
* NecessarilyEvil:
-->'''The Philospher''': "I do not enjoy what I do, though I am not ashamed of it, and it would be no exaggeration to say that I am proud of it. It is something that has to be done, and somebody has to do it"
* PsychicPowers: [[ScarilyCompetentTracker Trackers]], [[AntiMagic Blockers]], [[BodySnatcher Transitioners]], [[{{Seers}} Forseers]], etcpp.
* TortureIsIneffective: A torturer/narrator explains that the worst torture of all is just describing what will happen. Later in the same book, torture fails to work, but only because the character being tortured [[ItMakesSenseInContext teleports out of his body]] first.
* TheVamp: Madame d'O, or at least she tries...
* UnreliableNarrator:
--> "Apparently I am what is known as an Unreliable Narrator, though of course if you believe everything you're told you deserve whatever you get."
* WellIntentionedExtremist: several (e.g. the Christian Terrorists)
* YouDidTheRightThing: Creepy when a torturer tells you this
** Edges into YourApprovalFillsMeWithShame.
* ZeppelinsFromAnotherWorld: Played with.
--> '''The Transitioner''': "I look up, hoping for airships. I always like when there are airships, but I can't see any." (later, on another world:) "Into the street. Still no airships. Dommage!"
