The Star King was the first Jack Vance book I read and turned me into a solid Vance fan. Hope you enjoy it.
I echo all the good things said about Flowers For Algernon. A real page gluer (glue-er?).
Reading the second book I started for Halloween -- Horror Times Ten edited by Alden H. Norton, a conscientious attempt to present stories never reprinted before, including a horror story by Max Brand. Before that I finally got around to reading Mary Shelley's Frankenstein. Someone else in another thread didn't like it but I thought it was great and well worth anyone's time.
