Ender ' s Game by Orson Scott Card . I was never really into SciFi , but this book , and the subsequent books to follow , had a cult following so I had to see what the hype is all about . Card does such a great job describing the psychology of his characters that you completely empathize for each one of them and understand the ones that you wouldn ' t necessarily empathize with . The movies completely ruined the book because it ' s a much longer process before the war actually happens , but the writing is amazing and there ' s a few quotes that I want to get tattooed on me somewhere from the books . I was getting into Psychology at the time too so it really hit home with a lot of different messages . Read them !
