There are a few ways to approach this:
1. By Character Name:
* If we're talking about the characters, then the alphabetical order would depend on which characters you're including. For example, "Harry Potter" would come before "Hermione Granger", but after "Draco Malfoy".
2. By Book Title:
* If you're asking about the books themselves, then the order would be:
1. Harry Potter and the Chamber of Secrets
2. Harry Potter and the Deathly Hallows
3. Harry Potter and the Goblet of Fire
4. Harry Potter and the Half-Blood Prince
5. Harry Potter and the Order of the Phoenix
6. Harry Potter and the Philosopher's Stone (or Sorcerer's Stone in the US)
7. Harry Potter and the Prisoner of Azkaban
