order of the books to read

[Joe]

This really isn't the place to ask this. But since I'm replying anyway I would suggest that since Harry potter and Charlie and the Chocolate Factory are aimed at children/teenagers they're probably a good place to start from an ease of reading point of view. Definitely don't try Les Miserables until near the end of your list. I read anything put in front of me and I still haven't managed to get through that! Also maybe The Hobbit, by Tolkein. I don't think its on your list but that was aimed at what we would now call the young adult market. Of the non fiction on there Bill Bryson might be a good place to start.

Yes, likely will be told to move to the Feedback group, certainly isn't a librarian issue.

But I would agree the "easier" ones on the list appear to be:

The Chronicles of Nardia Series (C.S. Lewis)
Peter Pan (J.M. Barrie)
A Series of Unfortunate Events (Lemony A. Snicket)
Alice's Adventures in Wonderland (Lewis Carroll)
The Wonderful Wizard of Oz (Lyman Frank Baum)
The Golden Compass Series (Philip Pullman)
Charlie and the Chocolate Factory (Roald Dahl)

Towards the end of your reading I would put the heavy classics like:
Les miserables (Victor Hugo)
Crime and Punishment (Fyodor Dostoyevsky)
The Three Musketeers (Alexandre Dumas)
The Count of Monte Cristo (Alexandre Dumas)
The Man in the Iron Mask (Alexandre Dumas)
Moby Dick (Herman Melville)
The Iliad (Homer)
The Odyssey (Homer)

I would also try searching in the groups for a group for of non-native English readers looking to read more English. I haven't looked, but I would think one or two must exist.
