Authors I always turned to include Charles Dickens, Jane Austen, and Agatha Christie. I devoured Jane Eyre and Catherine Marshall's Christie, different as they may be. For humor I can't get enough of Wodehouse, Rex Stout, Douglas Adams or The Irish R.M.
There are plenty of fine writers now, and I keep looking for comfort books that fill my imagination as well as bringing relaxation. Not sure any can match the classics I've always loved, but it's fun to keep looking.
