Considering the sales flow of the Twilight book, and the others that follow, it was possible to observe the importance of marketing to such success. However, it is worth reflecting in this work on the extent to which marketing help in the sale of a literary work and up to what age group do these books influence and how do they act on people's purchase options. Are these works only another market phenomenon or would they have literary qualities are the questions to be noted.
