(They are kinda like the Twilight Saga..A girl is torn between to guys and it takes place in the future, Also the Midnighters By: Scott Westerfield is a series that is really good and/or Peeps By: Scott Westerfield is a fantastic book!
You should look into the Pretty Little Liars series (Pretty Little Liars, Flawless, Perfect, Unbelievable, Wicked, Killer, Heartless, Wanted, and Twisted (coming out in July)). Also you should read The Missing Series (Found, Sent, Sabotaged) and one is my favorites is the Maximum Ride Series (Maximum Ride: The Angel Experiment, School's Out-- Forever, Saving the World and Other Extreme Sports, The Final Warning, Max, Fang, Angel)................These are some of my favorites!
