In her introduction, she cites two reasons for having written the book: (1) to provide information about the legal system, and (2) to provide information about the study skills necessary for success.

These two themes are repeatedly addressed in this book. It is very tightly focused and dry, but if you push yourself through the book you will learn a lot. Ms Nygren starts the book with a hypothetical situation--in which you, the reader, are a lawyer, and a client comes in with a complaint about a restaurant's food--and then she takes you through the process of identifying the legal issues in the case, how to advocate for your client, et cetera. Though she addresses only very small portion of "the law"--the liability faced by a restaurant--the detailed and close manner in which she takes the reader through this portion of the law is of obvious relevance to the rest of the law.

Ms Nygren provides a very comprehensive introduction to the structure of legal reasoning, and the kind of thinking needed by law students who wish to excel in their studies.
