Goodreads Librarians Group discussion

I have updated the covers of all seven books. I have requested a change before but don't believe I'm doing it properly. Can you tell me how to go about getting all covers changed? Showing in the topic is the old cover. Here is a link to the new cover. Thank you so much for your help.

We only update covers for Kindle and Audible editions, if this is applicable please provide a link to the relevant edition on Goodreads and link to the corresponding listing on Amazon
