Series Linking Assistance + A Listing Merge?

[BookMojo]

Good evening! I have a new client with a series that needs some linking help. Could one of you fabulous Librarians give me a hand with it?

Also, when I went to pull the links for your series linking help, I noticed that he has duplicate listings for the third book in the series. Could you merge these as well?

Thank you in advance for your help!

Added books 2 and 3 to the series; someone else had already combined the book 3 editions.
