This is an excellent literary novel with a sci-fi element (but if you are not a big fan of sci-fi, don’t let that put you off, because the focus is much more on the characters than the science).
Joey and Jeannette are twin sisters. When Joey is fatally injured in a fire, Jeannette can’t face the thought of life without her – so she pays the good folk at LifeMedia to have Joey’s mind uploaded into a “BrightBox” (this is the main sci-fi element – but in most other respects, the world of the story is very similar to our own and the focus is very much on the characters rather than the science). At first it seems to have worked – but as time goes on, Joey starts to wonder if she now has more in common with other BrightBox “uploadees” than with “breathers” like her sister. On top of which, it seems that the technology may not be entirely bug-free.
Although it starts off relatively gently and appears to be primarily character-driven, the plot soon gathers momentum and I found it hard to put down. It also gave me a lot to think about – for example, to what extent do our bodies dictate the way we think and behave? Would we start to become different people if we no longer had human bodies, like the uploadees? An intriguing and very thought-provoking novel.

Oh and one more thing – for what it’s worth, I’m not the only person who enjoyed this novel. It has attracted a clutch of similarly positive reviews on Amazon too. See: http://www.amazon.co.uk/Corpus-Callosum-Anatomy-ebook/dp/B00CYP6YCC
