Thirding the recommendation for chronological order. I'm in the middle of re-reading them using FBReader on my Android phone. The 6M full sequences with images epub does take a very noticeable time to get loaded into memory whenever the FBReader app has swapped out. Also it doesn't show some semantically meaningful formatting like text with strikethrough. Bullet lists which used autonumbering bullets in the original are converted into plain bullets, but the subsequent text sometimes refers to the missing numbers.
