I was never not going to love a book with Library in the series name! 
 This is set in a world where the Library rules in place of a government. By keeping the knowledge contained in books closely guarded, and only available for scholars and those deemed worthy, it can both impede and advance societal growth as it sees fit. Technology is stunted, business advancements are thwarted and the Library maintains a tight leash on its citizens. The all seeing and all powerful Library seems like an unbreakable patriarchal structure, but that might just be what they want you to think. 
 I adored this unique world and found its politics surrounding the spreading of information and knowledge to provide intriguing points for discussion and thought, within the book. It did take a little while for me to acquaint myself with the particulars of the political structure, but once I had done so I was mesmerised with the layers to this fascinating governing regime. 
 This is not my first time reading Caine's writing and I have been previously unimpressed. I am so glad I decided to give her another go as the authentic characters, the thrilling plot, and most especially this extraordinary world all combined to both restore my faith in this author and provide a leading example of YA dystopia done right!
