I am in English in high school and received a list of books I will be reading throughout the year. I am trying to get them on bookmooch (a website where you can trade books for very little cost) and was wondering if there are different versions of the book. Our teacher provides us with ones, but i like having my own copy so i can write in it. so if there going to be a huge difference in in the book they give us to one i would get online? thanks!
