I recommend The Knife of Never Letting Go. 
 ***** 
 Terrifyingly Shocking. 
 This is raw dystopia! Bleak. Hopeless. Ruthless. By time i closed the book, i was laughing sarcastically. So much for running eh, Todd? 
 Patrick Ness didn't bother with formalities. The story started with a bang! At the end of chapter 3, i stopped reading because i was scared. I need to run. With Todd. 
 But of course i picked the book again. Each time i finished a chapter, my nerves are tingling with fear. My heart rate beats spasmodically. I am right there with Todd and Manchee!... Wait, am i Viola? Lol 
 The pace is fast, the characters are effective to their roles. I hate Aaron. Why don't you just effing die?!!! I cheered for Todd and Viola. C'mon guys, it's time to go! Run! I mourned Manchee, such a dependable, protective and loyal dog. That's not the exit i figured for you, buddy. *sniff sniff* 
 I didn't like the sci-fi twist in the story but it's forgivable. Also, I was pissed because the reason why Todd is running was only revealed by chapter 36! I was with Todd this time, 'why don't someone tell me what is effing happening?!! Why are the Prentisstown men are after me?!!' I wanna know too, Todd. 
 This book challenges the choices Todd has to make, his mistakes in the past, and his actions that will define him as a man. It also reveals how human beings are destructive within themselves, how evil they can become just to protect their secrets. 
 Want to know why Todd is running? You better curl up with The Knife of Never Letting Go together with a nice and comfy blanket. Because the truth behind the history of Prentisstown is chilling.
