From April 30, 2009: Which is worse?
Finding a book you love and then hating everything else you try by that author, or
Reading a completely disappointing book by an author that you love?
The latter, I think. There are a few books by Dorothy Dunnett that I simply don't like. A few novels by Dickens disappointed me: Martin Chuzzlewit, for example. After loving Lindsay Davis' The Silver Pigs with a passion, I was bored by a few of her later books.
But this is rare. Usually, if I like an author, I like all that author's books.
Though there are a few odd cases where an author writes two or three series, and I only really enjoy, or only read, one of them. Robert B. Parker, for example. I love the Spenser novels, more or less like the Sunny Randall books, but can't bring myself to read the Jesse Stone books. Why? For one thing, they aren't written in the first person - and that's a part of why I otherwise so enjoy the Parker style.
With Lois McMaster Bujold, I like her science fiction better than her fantasy. In this case, it isn't so much the style, as the characters.
