^The editing process may have been as rushed as the writing process.
I can't speak to this particular project, since I had absolutely no involvement with it, but I can testify that things get crazed sometimes.
I remember editing a movie novelization (which shall go nameless) where the studio unexpectedly moved up the release date, so that I suddenly lost months
out of my production schedule and the book had to go to press, like, yesterday.
I confess: I barely glanced at the final revisions before rushing them down to Production and, at the time, was preoccupied with trying to get the cover art approved ASAP.
This is less than ideal, of course, but publishing isn't always pretty. And I got the book out in time for the movie!
