I think it's not so much a single book, but that he writes long series of them with well developed characters that bridge across them. There is one series (Alex Cross) I'm listening to on audio book now that has at least 29 books in it. None of them are super great but its like comfort food ... you finish one and the familiar characters are all there when you go back for the next. So this is the secret to have people buying huge numbers of books ... you always want the next one in the series. Mind you, I borrow these for background listening / when I go to sleep at night. I would never spend the time on them as a focused activity.
