I used this for my Extended Project Qualification studies, and I can safely say it absolutely helped my research. The editing of Booker's writing to a simple, layman's style of work is easy to follow, making it easy to reference and analyse. Whilst sometimes the studies are a little too short, I feel that as a round study of dystopias, it's a fantastic resource unparalleled elsewhere. Quick tip: don't buy it. See if you can source it elsewhere; it's good, but not worth £80 (the price it is right now). I found it by sourcing it through my college library, and that suited my purpose perfectly.
