Best Fiction book

I have always read book that shapes our mind, but now I want to read some fiction stories. Not only science fiction, but also something that tells a fictional story of a warrior or something similar to it. Please give some suggestions. Suggest some of the best books that are not very expensive, under Rs 500. Yeah! I have a budget issue because I am still a student, and my parents don't like this book-reading habit, but I love reading books.
