I finished Tom Perrotta's The Leftovers during this hour. It wasn't the poor ending that I thought was coming, but I wouldn't really call it a satisfying ending either. The ending left the plot unresolved. I would have preferred a neater ending.
I started Doubt a play by John Patrick Shanley. My total pages read for hour 19 was 66
About three quarters of the way through the hour I suddenly became sleepy. My eyes are heavy and I find myself rereading sentences because my attention has wandered. With five hours to go, I am starting to waver a bit. Hopefully my second wind will come along soon.
