This is really very good indeed.
Enough material here to get up and running with a low level (1-9) campaign in jut 48 pages. If you are happy with a mostly humanoid characters and monsters being very rare one off creations then this really is all you need.
If you like having fights against monsters by the barrel load then you wll need to get hold of a the Monster Manual or similar to give you pre-generated creations.
The book is beautiful, the layout logical and overall this is a job well done.
