Before you buy any of these books, it is a good idea to look at them at an online shop like Amazon. You can click on the book and read the first few pages to find out what it's like. This will help you to decide how interesting the book might be and how easy or difficult it might be for you to read.
I really hope that enjoy these books and please let me know how you get on.
