This is what happens when you still have the first copy of a book you love after almost 30 years and many re-readings:
The cover comes off and gets taped back on, the spine is mangled, and there are pages that may fall out at any time. A book gets like this for being loved, and Dune is one of my all time favorites. Very few things have ever come close. Written a year after I was born, it's held up really well over the years, and it's time to read it again.
I need to be careful, though. I have a tendency to gulp it down in one or two sittings, failing to savor the concepts and prose in favor of diving headlong into the plot.
I'm giving myself this treat - rereading Dune after several years - because the other things I am reading at the same time are going to be tough sledding. I'll have to ration it out carefully, and work at limiting my time with it. If I don't it will be done in a few hours and nothing else will have advanced at all.
