I've just finished reading a brilliant, quiet, but in its way brutal and chilling novel, Thomas A. Savage's "The Power of the Dog."
Sometimes info on Amazon serves you better than leafing through the items in a bricks-and-mortar bookstore. (I've always found that I'd need to read for a bit longer than I realistically have, in order to decide whether I like an item or not.) In this case, what put me onto it was seeing on the website that Savage had said his favorite novel was "Mrs. Bridge," by Evan Connell. That novel, too, though in an entirely different way, is quiet yet in its way brutal and chilling. Both are startlingly and yet unobtrusively well-written.
Obviously, both very highly recommended.
