This is a book written by Nicky Singer in 2006, four years before she wrote her award winning Feather Boy, and what a difference four years makes!
GemX is the story about a dystopian future in which the genetically modified form the new elite and the unmodified (called Dreggies) live in slum like conditions, often going without even running water for days on end, and denied access to medical care for "eradicated" diseases (those that the enhanced no longer get).
The basic premise has been reprised many times, of course, but as this book is 11 years old, it comes before many of the more recent versions, although 9 years after the movie Gattica, so it is neither greatly original nor hugely derivative.
Singer does work hard to make her world distinctive. She has a mountain of vocabulary, to the point of distraction. She has a dictator who is weird but not quite President-Snow-Evil. The enhanced live sterile lives without human contact, and eating pills instead of food. A lot of that just seems odd, unlikely, but clearly an important statement in the polemic of the book.
Mentioning the polemic of the book, it very much lacks subtlety. The inequality, and what is lost is very much pushed in your face. There is no mistaking the point the author wishes to make.
In any case things go wrong with this future society. Maxo, who is perhaps the protagonist (more on that in a moment) discovers a crack in his perfect best of the best GemX face. He quickly searches the net to discover that this is a wrinkle, which is unheard of because he is just 16. It soon emerges that this fault is occurring in all the GemXs, and so his father fights to find a fix, while darker forces move to have the whole generation eradicated in what will be blamed on the Dreggies as a terrorist attack.
The plot meandered along, and there are other plot lines and other characters. There is Gala, a Dreggie girl, and her siblings, and a clone bred to be a docile slave who is finding rebellious feelings. The problem is that the story is told from each of their perspectives, and it was not entirely clear who the protagonist was. Occasionally there was even mid chapter head popping, and this seems to be the major flaw of the book which also slowed the story down.
Ultimately the book was not that exciting and the end, whilst perhaps intelligently open, left me thinking "meh".
I bought this book second hand years ago, and it sat on my shelf ever since. Having forced my way through it, I was left thinking that maybe I should have not bought it in the first place.
Maybe that is too negative a comment to leave this review on, so I will say that Nicky Singer's strengths as a writer were definitely foreshadowed in the writing here, and she was clearly inventive too. I cannot recommend the book, but it is not the worst thing I have ever read.
