Query: Disappointing...

I really loved her earlier books, but I've noticed a sort of slide lately. The past three releases, "Shem Creek," "Pawleys Island" and this latest one have an ultra-simplistic viewpoint. The plots are becoming less plausible, and for some reason, I am not sympathetic towards the main characters. "Plantation" and "Sullivans Island" were so rich and fulfilling that I feel as though the author is now just adding water and stirring.
