I read this as a book last year (review). I had planned to read this series for years and while I liked the book, I remembered very little of it going into the audiobook. After listening to this, I only really remembered the first half of the book. I had no memory of the second part. I had to pick up my copy to verify that it was my terrible memory and not the book I had.
I enjoyed the book a lot more on the second readthrough. I finally understand what Amber is and I want to know what will happen in the rest of the series. Recommended if you haven't picked it up.
