Fantastic beasts and where to find them

[Theodoreb]

I've looked online but cannot find out is there any books written by J K Rowling about fantastic beast series please?

It is this book - en.m.wikipedia.org/wiki/Fantastic_Beasts_and_Where_to_Find_Them

Thank you but That's not what I'm looking for I'm looking for the book the new films are based on.

That is the book that the films are based on

It's not a story, that is the book.

There's the screen play books of both Fantastic books. The films are based on the fictional book by Newt Scamander and then here is the screen play edition of both films.

The films are based on a Fictional author (Newt Scamander) and his literary work which was referred to in the Harry Potter novels. The actual book doesn’t exist.

There are books of the films, but its the screenplay rather than an actual story.

Thanks all I was just as to what everything was.
