I believe I get more enjoyment about reading these storys the second time. I, too have a tendency to speedread. It is a bad habit, picked up from my years as a teacher, not reading for pleasure, but reading student's essays and refeence material for lectures. I fend, however, that in speedreading for pleasure, I miss many of the subtile inuendos and hints that the author has worked so hard at inserting into the chapters. It is only by reading a second time that I am able to pick up many of them. I also have some trouble reading a story by a British author, most of the British words I am familiar with, but every once in a while a different meaning sneaks into the word usage and I have an unfortunate tendency just to skip my eye over the offending word, so I miss much of the 'under current' expressed in the chapters, but by re-reading I can slow down enough to take the time to look up the offending word in a British\American dictionary and thereby enjoy the author's intent more.
