1. Harry Potter and the Sorcerers Stone
2. Harry Potter and the Chamber of Secrets
3. Harry Potter and the Prisoner of Azkaban
4. Harry Potter and the Goblet of Fire

I have read the first 3 Harry Potter books.
( The small one, bottom right, is the British version of Number Three,
"The Prisoner of Azkaban").

I obtained a copy of the latest volume on the first day of issue
and began reading it immediately.
