This book 'transitions' the split between Iain Banks' non-sci-fi output & Iain M. Banks' vast space operas, presenting a sci-fi tale with a contemporary setting.
It is based on the premise that a virtually infinite number of parallel dimensions does indeed exist. The inhabitants of one of them have discovered that by ingesting a drug called Septus, they can transport their consciousness into the bodies of unsuspecting people in other dimensions & thus meddle with the socio-political development of other Earths. They have therefore formed The Concern - an organisation designed to strictly control the use of 'transitioning' & ensure it is used to benefit other worlds. But since The Concern's High Council plays its cards suffocatingly close to its chest, can they actually be trusted? Or could some of its members have adgendas of their own? And how can anyone decide what constitutes the greater good anyway? These are questions one of The Concern's assassins has to find answers to when he becomes a piece in a deadly game between his employers & an enigmatic renegade.
The Concern echoes the interfering, egalitarian Culture of Banks' sci-fi novels but as its members are all merely human, The Concern is murkier & harder to trust. The idea of parallel worlds has been used before, notably in
The Adventures of Luther Arkwright but never with Banks creative flair & ability to analyse the deeper implications in an entertaining & thought-provoking manner. Yet despite the virtually infinite variety this backdrop provides, the plot is a relatively straightforward one.
Quite appropriately, given the books' subject-matter, the narrative consists of separate threads from different characters' points of view. Banks has really gone to town with this approach, starting with 3-4 such perspectives but later adding more. This is a style which ordinarily results in the reader racing through sections relating to characters/plotlines they like & glumly wading through the rest but in Transition, I found each thread to be equally captivating & enjoyed working out how the disparate pieces fitted together in the overall picture.
I have found that many of Banks' novels (such as
The Business) consist of a story which can be summed up in 100 pages, fleshed out with 300 or so pages of florid descriptions & background details. Transition, however, never meanders far from the main plot. It's an expertly-crafted, entertaining & thought-provoking read, which remains gripping throughout. In my view, it's one of his best.
In short, the transition from prologue to epilogue was a thoroughly enjoyable one.
