I love this series and the characters. The problem that I'm running into with these later books is that they don't feel 100% cohesive. It took half the book for me to determine whether Vin or Izzy was suppose to be the main character. I like the glimpses into all the other characters, but I feel like those glimpses are just getting longer and longer. I enjoy them, but they do take away a bit of development time for the main characters so I'm left feeling like something minor is missing from the story every now and then.
