I am a high school freshman who just finished the school year on this Tuesday, and I will be a sophomore next year. The school requires every grades of students to read 3 books during the summer for next year's summer reading assignment at the beginning of the year. So, I had read 3 books last year, and I will read 3 this year. My question is: whenever I buy those books from the book store, there is always a line of sentence on the bottom of the cover says: "A New York Times Best Seller." What the hell is that? Why is this thing appear again and again (6/6 of my summer reading books have that) in those "teacher - recommend" books? Is it some type of award or something? I am just getting annoyed by that? Will the thing increases the prize of the books? I spend 40 bucks only on 3 books (I don't like to borrow books from library, they're old and dirty). However a SAT Prep. book with 1,000 pages only cost 20 bucks.
