Time to revisit him. I had to read him in high school and while I made it through "Starship Troopers", I only got this far through SiaSL: "John Valentine Smith was born on Mars."

I'm not thrilled with his later work (other than "Friday"). His short fiction is quite wonderful too. Try to locate his collection of Future History stories in "The Past Through Tomorrow". For a collection of short fiction and essays, see "Expanded Universe". All-in-all some really good stuff.
