This supplement is certainly a departure from the norm in your average RPG system. Traditionally a supplement such as this would contain a bunch of new adversaries, allies, equipment, stats etc and whilst this does indeed have this, it is not it's focus. What I found this supplement to do and do well is enable you in a number of ways to turn the world of your players upside down and give it a good shake, something this entire system is great for.
Typical of this publisher, the writing is easy and fun to read, being well set out and not padded out with a lot of things you don't need.
However, although good value for money it isn't a 'must have', but it does as it was intended, supplementing your game.
