Cloud Atlas

Cloud Atlas by David Mitchell (no not that David Mitchell - the Shakespearean comic married to Mrs Only Connect). This is an extraordinary novel which weaves 6 separate stories into one novel and subsequent film. There's even a Facebook group called Cloud Atlas Changed My Life. It didn't change mine but I look forward to each new book by David Mitchell because his particular brand of speculative fiction (is there any other kind?) uses the unreliable narrator and shifting multiple personalities to continually disorientate the reader. When it works it provides an exhilarating kaleidoscope of parallel lives, when it doesn't it sucks.
