Q: I like the book Castle In the Attic because it was very adventurous. My favorite part in the book was when Mrs.Philips gave William a gift. Do you know what the gift was? Can you figure out what it is? I recommend this book because Castle In the Attic is a very exciting novel to read.

Q: Despite all the hype and negativity due to popularity backlash none can honestly admit that Asimov made a mundane focus for his writing passions when he wrote and then published the stories that comprise 'Foundation'. Since I read this epic book in eighth grade it has stuck with me due to the relation of structural decay and rebirth in a future universe that mirrors our own rather perochial existance. The serendipity and foresight combining thought and action to build a better future for mankind in the Milky Way galaxy will leave the experienced, educated readers feeling they have witnessed the true future of our reality. This is a truely brilliant effort of science fiction as are many of Asimov's early works. Shame on the nay sayers.
