I started reading heinlein juveniles in the fourth or fifth grade. I think Red Planet was the first book of his I ever read, but I know that Between Planets, Podkayne of Mars, The Star Beast, Have Space Suit — Will Travel, and Citizen of the Galaxy all came soon after. By middle school, I was reading his adult stuff, starting with The Door into Summer and then moving on to read just about everything he ever wrote. At the time I read Stranger in a Strange Land (and, to a lesser extent, Time Enough for Love), I thought I was onto something really profound. What’s interesting, looking back, is that — while both of those books stand out as very important works, they aren’t the ones that stick with me, and they aren’t the ones I go back and re-read now.
