It is a common misconception that book reviewers only read the first and last chapters of a book. This could not be further from the truth! In reality, most reviewers try to read the entire book before writing their review. Of course, there are always exceptions to this rule – sometimes a reviewer will put down a book before finishing it if they find it to be particularly poor quality. However, in general, reviewers do attempt to read an entire book before offering their opinion.
One reason why reviewers may choose to finish a book before writing their review is because they want to be able to offer an accurate assessment of the work. It would be unfair to judge a book based on only part of its content; after all, you wouldn’t want someone else judging your work in that way! Furthermore, reading the whole book allows reviewers to get a sense of the author’s overall style and tone, which can be important when considering whether or not to recommend a particular title.
Of course, reading an entire book takes time – sometimes days or even weeks – so it’s understandable that some reviewers may not always have time to finish every single one. In these cases, reviewers will typically focus on those parts of the book that they feel are most important or representative of the work as a whole. As long as they make it clear in their review that they haven’t read the entire thing, there’s no harm done!
