I've read Gravity's Rainbow several times, and have read selected pages and passages in the book many, many times. It's the greatest novel I've ever encountered, an absolutely amazing book that rewards multiple readings and inspires research and analysis. The more I think and learn about the book, the more amazed I am at Pynchon's achievement, which seems to me at least to be almost ultra-human. How can any one person master the encyclopedic range of topics and technologies in GR, and integrate them all so seamlessly into such a beautifully and masterfully written book?Which I hope provides some context for Robert Crayola's Gravity's Rainbow Handbook. Crayola has managed to summarize the narrative (not an easy task), provide historical background for the story, and catalog a good number of the main characters (and there are hundreds of characters name-checked in GR), all in a concise format that's a joy to read. Crayola's handbook added both to my knowledge of, and appreciation for, the book. Well worth the ebook price!Mr. Crayola, I hope you're working on another handbook. May I suggest Against the Day, which might be Pynchon's second greatest novel (it's certainly the longest), and one I don't think gets the attention and praise it deserves.
