...strong? no twilight please. i want the main character to be a girl and for her to be strong and not some sweet kind girl that needs help from the guy.
I'd say the Vampire Academy series (WAY better than twilight in my opinion). The main character is kick ass and doesn't need a guy to protect herself.
A lot of people may be put off by vampire stuff now-a-days but this series is AMAZING! It's funny, sad, and has ton of action. It has both romance and a solid plot.
