Hey hon. you're going through exactly what I went through when I first read The Godfather. Of course I had already seen the film, had NO IDEA that it was only written up until GF Part ONE as we know it from the movie. Th novel ends where The Godfather ends. And so thats how it is my dear. I know..I know..you want more , but trust me, i've lookd it aint there. Yes, original screenplays:GF@ & GF3.
