10. Divergent by Veronica Roth
9. The Hunger Games by Suzanne Collins
8. The Iron King by Julie Kagawa
7. Jurassic Park by Michael Crichton

I realize several of these are popular choices so you may have already checked them out. BUT, if you haven't, you really should. If you have seen the movie....try the book....in the picks above the book is way better!! I guess I really didn't consider myself a sci-fi fan, but I enjoyed all of these choices, so maybe I am a closet sic-fi fanatic!!
