I have to say that at first the beginning of Outside In seemed to bore me and kinda drag a little, but by the end i was totally asking for more!!...You'd think everything would fall in place after the rebellion, Trella would make an assume her position as a leader, the uppers and Scrubs would be united for one cause...But turns out there was a new enemy lurking, and it's not like Trella figures out who the exact enemy is at the beginning or even almost thru out most half of the book. We don't really know who the common enemy is until almost the end, and i like that she has us guessing!! 
 When you think you know who the bad guy is, you're like 
 son of a **** 
 then you find out you were totally misinformed!!...The actual supposedly good guys were kinda the bad guys because they were totally misinformed but then fix their ways!..i don't know if i'm making any sense but you'll get what i mean when you read the book...i'm trying to hint and the plot without really giving too much away! 
 So anyways i cant wait until the next book!iTitle seems like it's gonna be kinda tricky!!
