I just started reading Tess Gerritsen's "Jane Rizzoli and Maura Isle" series.  I loved the first two books: "The Surgeon"  and "The Apprentice".

What I want to know is "Does she or doesn't she keep up the same high quality of work though the rest of the series?"

I feel some author lost interest in their own story after the third or fourth book.  They just keep writing the books to make money.
