ADDING BOOK NUMBER TO MY SERIES > Likes and Comments

Hello, I am needing to add a series title to my books. Tower of Ash (series title). to Tower of Ash and Darkness and Tower of Ash and Betrayal.

I am hoping to label "Book One" to Tower of Ash and Darkness.
Add "Book Two" to Tower of Ash and Betrayal.

I want my readers to know which book to read first and order them.

Is the series on Goodreads yet? If so, please provide a link.
Otherwise link to the books

If you just want to add it to the title, you can do it yourself.

The books are on goodreads. The series title isn't isn't.

I am wanting to add series name "Tower of Ash series."
Tower of Ash and Darkness is the first book
Tower of Ash and Betrayal is the second book.
