"unique"
somehow I got to be 38 without every reading this. Without really even knowing what it was about. I'd heard wacky things about Ayn (and her followers), but was pleasantly surprised by the book. The scale was refreshingly endless... her writing style is unique, wavering from the authentic depths of story telling to the shallow puddle of smut-fiction... But as a fan of Sci-Fi I am used to that. In many ways it is an Asimov-ian sci-fi adventure set in the techno-industrial beginnings of our country. in short, wish I'd read it earlier.
"sticky"
it isn't anything new necessarily, but I have found that ideas as described and the examples used to illustrate provide a lot of comfort and support for a dad on the "firing line" (scratch that) for a dad with an incredible opportunity to focus on myself!
