THIS book was a monster to finish listening too... but I am so happy I finally finished it. I def thought listening for the first time to this book could have been a better experience if i just read it. but i really enjoyed the storyline. I liked the pay off emma and jules character and also where their characters went. I also loved all the new characters we met and love how mark tied into the story. I really loved the mystery that need to be solve. I also thought this book unlike heavenly fire, relied a lot less on Clary and that crew only in very key moments. I would have liked a few more tie backs but this book was so well crafted. Def need to read the next book soon!
