"The volume" - limited subject that refers to only one book (in this context). Only one book was a bestseller, the others did not sell a lot of copies.
"Every volume" - larger subject that includes each book in the series, but compares their individual sales amounts as bestselling books.

Koir, thanks!
Now, I see that "every volume" doesn't mean "every book in the world".
Thank you.

"Many of her readers" is the correct form as she is an author. Looking at just the words, it's easy to think that people are reading *her* and not her books. But in this context her status as an author means that people read the books she writes, so they are "her readers".

I see. You say "her readers" and it doesn't mean the people read her.
Thanks.

The proper expression is "I wrote about...". You talked about a similar subject in an earlier blog post, so it occured in the past.

It should be a past tense. Not a perfect tense. OK.

Apologies. It was a very formal, restrained way of saying "Instead of just saying it's wrong, try correcting it so the person will understand more."

Now, I see. Thanks!
