What book is first eternals or tantalize?

It's impossible to say which book, Eternals or Tantalize, is first without more context. Both titles could refer to:

* Series: There could be multiple books in a series called "Eternals" and "Tantalize." We need to know which series you're asking about.

* Authors: There could be different authors who wrote books with the same title.

* Genres: The books could be in different genres.

Please provide more information:

* What are the full titles of the books?

* Who are the authors?

* What genre are they in?

Once you provide more context, I can help you determine which book is first.
