What a brutal and horrific depiction of a future in which humanity has developed a drug that prevents ageing and illness. In order to combat overpopulation and resource shortages having children is prohibited except for those who do not take these longevity drugs; a life for a life, so to speak. Illegally born children, termed Surplus, are taken away to be raised to be slaves for the legal population. In one such training centre we meet Anna, who is about to learn that she is worth more than what she has been raised to believe. 
 I really enjoyed this dystopia; fast-paced, solid plot line with an exciting climax, interesting (though sometimes frustrating) characters and a terrifying premise that provides a great backdrop for a range of compelling themes and social commentary. I particularly liked the exploration of the effect of brainwashing on creating individuals that are not only passive but complicit in their own captivity and torture (a very harsh look at humanity, but one that often felt realistic). I'm intrigued to see where this series goes as we undoubtedly delve further into this books first stirrings of social unrest and rebellion. 
 I would recommend to those who enjoyed The Haven by Carol Lynch Williams and Unwind by Neal Shusterman.
