So it turns out Natsu and the book are still connected. Called it! I don't want Zeref to achieve his goals just yet I want everyone to find about Zeref and Natsu being brothers. For there to be a cool fight between Zeref (with Fairy Heart's power), the fully awakened E.N.D. and Acnologia. But I know that's just wishful thinking as I can tell something will prevent all that from happening.
