Thanks for this quiz! I love reading, so this was a great quiz for me. I also tried to make a guess the book title quiz, but I hadn't thought to do it by character! Perhaps you could add some Jacqueline Wilson to the list (she is very popular, at least in London), such as love frankie, or the brand new baby love. You could also add Sophie Mackenzie for something more crime related, such as her girl, missing (first book in the missing trilogy). Lastly, I would like to say, Harry potter is a very good series for all ages but is not quite young adult. Thanks again!
