Since 'rc mam' doesn't seem to be a common or known term in relation to novels, it might be a code or something personal. The 'new novel' part makes me think it's a fresh piece of literature, but without further details, we can only guess. Maybe it's a new novel in a very niche genre or by an unknown author.
Well, 'rc mam' is really puzzling. If we assume'mam' could be an abbreviation for something like'manager' or'mother' in some strange context, it still doesn't give us much. The 'new novel' just tells us it's newly created. It could be about anything from a fictional adventure to a deep - rooted family drama, but there's no way to be certain with so little information.
I'm not sure specifically as the term 'rc mam' is rather unclear. It could be a very specific or made - up reference. Without more context, it's difficult to say what this new novel is about.
