His earlier works were amazing, I grew up on "Starbeast" "have spacesuit will travel" "the rolling stones" "spaceship gallileo" "farmer in the sky" "Starship troopers" etc... and many more that I cant remember the titles of ... My parents read them to us before we started grade school... His best works were the "juvenile" ones.... however, his later works were very bad.... With the exception of "the 5th column" and "moon is a harsh mistress" he never seemed to write any "adult" sci fi... "stranger in a strange land" I thought was awful, "Farnhams freehold" was just insane drivel...I couldnt get through "Friday"....

I was told that he had had a stroke and that afterwards his writing declined in quality..... anyone know if this is the case?
