'I am changing, fearfully changing'

Have had a niggling feeling all year that something was odd. Off. Borderline wrong. Finally realized what it was. My English reading for 2007 to date- China Mieville, Patrick O'Brian, Garth Nix, Wilkie Collins, John Crowley, Peter Ackroyd, Wilfred Blunt, Robert Holdstock, Booth Tarkington and currently Neil Gaiman.
