You're welcome.
I have read Martina Cole, but years ago. Cannot remember which book(s). I think you would like Robert Tanenbaum.
Well enough Off topic. Don't want to be reprimanded
You might consider looking into formatting of ebooks at this point. I have my conversion preferences setup so that most books have the same justification, line breaks etc. Makes a big difference to me in the comfort of my reading experience.
Another place calibre excels is in downloading metadata, series, series numbers etc. If you haven't tried it you should.
Of course you may already have done all that.
