It just occurred to me. If I am a Good Boo and only allow myself one story per day, "Endless Nights" will overlap with "Monstrous Regiment," which comes out on the 30th. A new Discworld book and a new Sandman graphic novel read at the same time? The horrors! I don't think the human body was built to withstand such squeeworthyness!

I shall permit myself two per day, and they shall go back-to-back.
