I haven't planned this very well, of course. I basically have no hope of getting the diagonal until maybe the end of July if I get and read the UK edition of The Hanging Tree, so my best prospect would be to continue with the topmost horizontal (that's where most of my planned reads happen to fall in). Oh well, I'm still having fun!
