"shake it out shake it out 
 shake it out shake it out 
 uoooh 
 it's hard to dance 
 with the devil on your back 
 so shake it ooout" 
 --Florence&the machine, Shake it out. I think this song suits Izil perfectly. 
 This book is awesome, I think everyone should read it. Best angels versus demons' story I've read so far. Luckly, FOR ME, book 2 is my next reading! (after I finish, with all my strenght, CoLS.)
