[I received this book via LibraryThing Early Reviewers]

I have to admit that I had some trouble when I started reading this novelette (roughly 70 pages). Maybe my command of English language was not that good, but I did not understand what was happening. Slowly the plot became clearer, and besides a short lapse of understanding at the beginning of the second section, when the talking protagonist changed, I quickly ran through the pages till the end.
The setting of the book, which I understand to be part of a series, is something that many of us fear will happen in the future: brain implants for the "best" people who will live in the main cities, satellite cities (like the enclave which gives the title to this book) where people work in recycling and feeding the rich, and migrants, like the main character Caleb, who desperately try to become part of the main city. All of this is just hinted in the book, since this is not the main interest for Anne Charnock. There's some text which seems a bit patronizing to me, but in general the book is worth reading.
