Really? Am I the first to be the pedant who points out that he name is CornwEll with an E not an A, as in the English county?
That aside, anyone who reads Patricia's books will know that, unless indicated otherwise, they all follow a single story thread about Kay Scarpetta, her work, family and friends. They can be read as standalone books, but always have references to things that have happened in previous books.
Yes, I am a longstanding fan, and eagerly await each new installment, usually released in the UK each November, although, I found this year's offering in Tesco in October.
I am an avid reader, getting through between 3 and 5 books a week, and do love a good Val McDermid, Karin Slaughter, Kathy Reichs, James Patterson, Harlen Coben, Lee Child, Karen Rose, etc, but Patricia Cornwell will always be my favourite.
