I am the author of the novel document class.
Due to some change in one or more other LaTeX packages, novel now crashes. This behavior is as of the last couple of weeks. Novel certainly did not crash prior to that. The crash is fundamental, in that the user's document content does not matter. It is not due to any change in novel.
My own archive compiles with older TeX code (as of a month ago), but does not compile with current TeX code. Thus, the problem is with the other TeX code.
Since I introduced novel, twice I have had to revise code, to compensate for changes in another package. This time, no. It seems that the package(s) causing the crash are not necessary for novel's purpose, but they are automatically loaded whether novel likes it or not; then novel crashes.
I have requested that CTAN remove novel. Sorry about that, but I do not have the tme or inclination to chase this.
It may be that some users will find that novel compiles, only to discover that it fails after TeX update.
