[Urbane Guerrilla]

I think I've read about all of them, juvie and adult. Starship Troopers I found seminal -- it has had a huge influence on my philosophy of life to this day, forty years and more later. Time Enough For Love I think was his masterwork. Do also check out the retrospective Grumbles From the Grave if you can find it -- Heinlein and other ess-eff pros talking about Heinlein. Spider Robinson's essay is particularly interesting; he says Heinlein tended to start him awake late at night, thinking on things RAH said or wrote. Ably rebuts the notion (a very mistaken one) that Heinlein was some kind of fascist, which was something Paul Verhoeven simply never understood in his moviemaking. Starship Troopers must have an American director. Europeans aren't going to grok ST in its fullness; it is a very American sort of story. Heinlein's thinking is very libertarian -- check his views on ID cards, to let one example stand for many.
