Are you kidding me?Falling in love AGAIN?Ok,fine,but...this ending is the worst thing of all,even worse than the horrible cliffhanger ending in Delirium!*sigh* 
 Compare to the first book,the second one is the totally different types and feelings,Lena grows and changes herself and tries to survive,she's no longer Alex's cute girl but Julian's stout companion yay! 
 But before grabbing Pandemonium,make sure you get Requiem besides you...!
