Subject says it all - does it really matter? I am borrowing them as they become available from the Library. Son is currently 3/4 way through LW & W at school (teacher reading it to them) so have lined up a couple of others, but won't be in sequence.
Now that he has LW&W under his belt, so understands the concept of what happens, and the names, how much knowledge from other earlier books do you need, I can't remember (it is over 30 years ago that I had them read to me!)
Many thanks
