In my defense, the Sci-fi stuff I posted is not really along the lines of dragons and robots. First Immortal deals with cryogenics, and DNA manipulation, work that is being done now. Truth Machine is about using science to build a 100% effective lie detector, and the possible impact that would have on the near future in the science and political realm. Pastwatch, I admit, is straight sci-fi, based on possibility and probability as it relates to the implications of history on the present. Good story, nevertheless.
And yes, Dune is hard-core sci-fi, but in its defense, is the grand-father of other-worlds sci-fi. Star Wars, fully developed. It is as influential to Science Fiction as Tolkein was to Fantasy Fiction. Philosophy, religion, politics, theory of ecology, and speculation all rolled into one... with some great fight scenes too! Hmmm, that just about hits all the things you don't want to read! Haha!
Not saying you HAVE to read them, LOL! but Sci-Fi is not always dancing green women and genetically enhanced humans ripping off their shirts... ;)
