New title to existing series

[J.W.]

Can someone help me add a new release to an existing series? Or if I've missed something obvious, can you point me in the right direction to edit myself.
The new book is: https://www.goodreads.com/book/show/5...
and it should be added as the third book in this series: https://www.goodreads.com/series/2898...
Thank you in advance for any assistance you can provide...JW

Done, only librarians can create and add to series.
