Laravel and Vue Register Data to the Database

I am making a project shall I say, writing a book. The user can create a book and in the first page, he/she will put the Title of the Book, the description also the book cover and I used Vue Components to do it and so far it's working.

How can I make a second page that when the user clicks NEXT Button, the user can start writing the content of the book and when he/she clicks save, it will save to the book that he/she currently working?

Note: On the first page, when the user clicks NEXT Button it will save to the DB which I already finished it and works perfectly. Thanks!
