I recommend The Ask and the Answer. 
 ***** 
 DEVIOUS. 
 Okay. So I should know by now that reading this awesome series will take a looooot of patience on my side. Because The Ask and the Answer simply won't stop pestering me with its mystery, intrigue, and otherworld-liness (is that a word?). But what a blast it was when I reach the final chapter! Mr. Ness? you are one mischievious and twisted author. Oh yes, you are. =) 
 Reaching the first half of the book, I didn't like where the story was heading. It was like Todd and Viola are being separated by circumstances (if not fate). It has that "star-crossed lovers" effect i that i could do without (minus the romance part). The push and pull whether to trust each other or not is annoying but it is necessary to build the climax in the end. 
 And what a wickedly brilliant ending! Stupefying, to say the least. I love Todd and Viola even more. and surprisingly, my heart broke for Davy Prentiss. Yes, you read that right. Davy. *almost in tears* 
 I will try to recover first before plunging into the final book, Monsters of Men. and I am so anticipating what Patrick Ness has in store for me. *squeals*
