Three words. This. Is. Excellent. 
 A really good book. Romance, makes-your-heart-race-thrill, suspense, action, all in good doses. This book covers everything the previous one doesn't. 
 Minor spoilers warning: 
 The rebels cause up quite a stir and so does America, and it's your classic girl torn up between two boys case, but I simply loved it, though the narration did get a little boring in the middle, but I bet that was just my action craving good ol' self. No sweat. Good book.
