Reviews play an important role in revolutionising a product. Reviews can even promote or demote a product. The same is the case with the book reviews too. Book reviews play an important role in the success of the book, particularly if the author is new. Since many of the readers use the reviews as a deciding factor on reading the book, it should be taken career by the reviews not to include any kind of false information in their writings as it can cause serious harm to the career of the author. The reviewer has to give an overall summary of the book together with evaluation of the major incidents in the book. The reviews may sometimes include certain forms of criticism but be sure that every point that is included in the book reviews are undoubtedly honest and such criticisms help to develop the skill of the author tremendously. Praising of the author does not stand good in the book reviews as it is can be easily decided by the public after reading the book. Thus book reviews should encompass all the necessary information and comments which in turn helps others to understand the importance of reading the book.
