I did read all of Margaret Maron's Judge Deborah Knott books in the order in which they were written, and, as they are a series and full of the same characters, who actually do grow and age, and a great big (she has ELEVEN (11) brothers and they have children) wonderful family, I can appreciate someone not being able to relate if they have not read books previous to the one they try.
I loved Ken Follett's WORLD WITHOUT END, and so bought the DVDs of the mini-series. Started watching them last night, and wouldn't you know, they have COMPLETELY changed the story. The book was darling and wonderful and would make a perfectly charming movie. In short, the book deserved better than what these film makers came up with.
