@Switch BlaydeThe "Blurb" for many stories, in particular, published books, the Blurb is not (often) written by the author, but by someone working for the publisher. It is to help "Sell" the book to people who likely have no knowledge of the author, nor any previous works.
Even on SoL the "Blurb" is sometimes written by someone other than the author.
I could see writing a "Blurb" as if it were First Person by (a, or the) MC in the story. That would likely be tricky; not appealing to some people.
The Blurb is for the Author to let people know about the gist of their story; Or a "tease" or other means of encouraging people to read their story.
Writing a Blurb in First Person might be a way of enticing people to read... Might.
