'Insignia' by S.J. Kincaid is a great sci-fi book the almost anyone can enjoy. There are many great plot twists and the book is very well written. I think that this is a book that everyone should have on their must-read list!
This book, Escape Velocity by Mark Walden, is a great book if you are into James Bond and advanced technology. There are a little bit of wizardry-like powers in the book. For example, Otto Malpense is able to directly interface with any computer, due to the organic supercomputer that was cultivated in his head. This allows him to help in rescuing Nero from the grasp of H.O.P.E, a criminal organization that was promoted by the government.
