Ray Comfort must have his own dictionary. I don't think anybody else would classify "Audacity: A Novel" as a novel. It's more like a short novella padded with lots of pictures from the Audacity movie and a long Q&A section with Ray Comfort. The point of making a novelization of a movie would be (besides making some extra profit) to transfer the story into prose and flesh out the characters in a way you can't do on screen, but this "novel" doesn't. It's just a retelling of the movie, with some extremely brief backstory added to Peter and Molly's childhoods and a minor subplot wih Ben, but they don't really add anything.
If you've seen the movie, and whether you liked it or not, this "novel" is pointless to read. I guess Living Waters are trying to promote this as a sort of tract for people to give away but I doubt many people will enjoy reading it. It's not well written or well told and just comes off as even more preachy than the movie.
