Author wants to amend errors to Blurb

[Rowanvale]

My Author has flagged up grammatical errors with the Blurb, and they would like to edit it but not sure how. If you could look into how myself, as the publisher can amend that for them, or perhaps even them doing it themselves.
Many thanks

If the author is a Goodreads Author they can do it themselves.
If not they, or somebody else, can post a request at 'book & author page issues' detailing the changes required and providing an acceptable source for confirmation.
