I was quite annoyed because of the price range between 3 publishers is really far. But, thankfully, Little Brown provides the middle price and the book is great! Before the book arrived, I thought the book would be super thin, but when it came, I think it's average. The quality of the product is really great, everything's perfect. I really recommend to buy this last and if you already bought it along with the 3 books, just don't open it (no peeking). The book contains spoilers from all of the 3 books! But, let me say this, the illustrations from the book are perfect! Totally recommend this book, it's super worth it! Thank you Periplus.
