So far so good! 
 I was really excited to get it, and according to my kobo I'm about half-way through :) 
 Oh wow, I finished it... and it was AMAZING. I can't remember how many stars I gave Delirium, but Pandemonium was better, if possible - and definitely did not stray to far into 'middle book syndrome' area. 
 The ending was although slightly expected, it still had me in tears. 
 Book 3 is too far away.
