Query: Not one of her best

I have always been a Belva Plain fan. I couldn't wait for her books to be published! After having read her latest two: "Fortune's Hand" and "After the Fire", I'm disappointed! Both of these books are just not up to her earlier works. I can't put my finger on it: is it the characters, the plots, the writing? They just left me with a blah feeling.
