Where would you count these books?

When doing this challenge, would you consider the Harry Potter series to all fall under the letter "H." Or, do you go by the title such as "Chamber of Secrets" or "Goblet of Fire?" I just started the challenge in August and have about 8 more letters to go, but I've been reading the Harry Potter series with my daughter & wanted to know where they should be counted. This is my first A to Z challenge. Thanks for any feedback!

Hi Cocoa. It's my first Alphabet challenge, too. I've read quite a lot of books that are part of a series.
I always count them with the letter they start with. The Harry Potter series is 7 books, so you can cross off 7 books from your list instead of just one, if you count the series as whole.

Here's a link to my challenge.
