I am a big fan of sci-fi

Ben Bova is a great author

Mars
Return to Mars
Jupiter
Death Dream

All very good books, and aren't very "far fetched" The stories could happen...soon. The first 3 are about Humans exploring other planets. Death Dream is about virtual reality.

Another author is:Orson Scott Card

The ender's game series:
Ender's Game
Speaker for the dead
Xenocide
Children of the mind, there are a few more

These also are sci-fi; about a child genius that was bred to destroy an entire alien species that was threatening Earth.

Also for Porsche reading "Ultimate porsche 911" and "Ultimate porsche 924/944/968" are very good. I'm not sure of the author.
