Goodreads Librarians Group discussion

Hello! I was trying to combine the two editions for my book "Vencida", the 2nd book in the "Sinergia" duopoly, and instead it combined this two editions with book one of the saga, "Vendida".

Can you help me undo this? I tried, but it doesn't work. If you go to my book page Vendida you'll see the two editions for book 2, the one with the blue cover. Could you please help?

Also, I neeg to add the second book to the series page. Thank you so much!

Separated. This was not an adding new books request.
