Top Ten Tuesday

This weeks Top Ten Tuesday is Top Ten Books If You Like… (fill in the blank with your favorite TV shows, games, movies, comics, etc)

So I decided to do Top Ten Books if you want to read Sci-Fi. These are not in any particular order and I don't think I have 10. Now I only put books I have read but I've got some more Sci-Fi in the bull pen. I am a Sci-Fi nut and there are probably books I'm missing on here. These are first ones that come to mind.
