I enjoy her books, too. But not too many back to back. I think I was reading the MacGregor ones as they were being published which did space them nicely for me (accidentally tried to read a couple thinking were new). Never anything I would go looking for, but, when spotted was always a "hmmm, a Nora Roberts I haven't yet read — she doesn't disappoint."
Roberts is a "doesn't disappoint" author for me too, or at least she was. I don't think I've read one of her new books in ages, unless you count her J.D. Robb books. She definitely follows formulas with her characters and stories, but those formulas consistently work. About the only thing that irks me in her contemporary romances is her occasional inclusion of paranormal woo-woo stuff.
