It is a strange and unusual book. I loved how nothing about the context is ever explained, just alluded to and it is assumed that the reader knows what is meant - the device draws you into the world of being "uplifted" "AFs" and "interaction meetings". On the other hand, it describes everything physical in such minute detail so you can almost taste, smell and touch that world. It is so clever about the consciousness of AFs too, and of course about the human heart.
