How to write a critical review? You learn to construct an argument, it is a focussed activity(in contrast with essay writing)
How to do it ? Describe the work and its topic, the author, the subject the relevance and who it is pitched at, be descpitive and short.
Explain "the craft" of the book , what the author brings to the field, the sources used and the approach, the arguments, the intention of the book, it is not a summary of contents, but an analysis of approach and intent.
Evaluate whether the goals are met.
Purpose, Why did the author write the work? What did the author hope to achieve?
