This book was superb!The characters were fantastic, well developed and really believable. The land and magic and people are awesome, the concept of the Grisha are a wonderful new spin on magic and "magicians". The Fold is a really different sort of evil that I really haven't ever read before and the idea of a Sun Summoner is just so cool! Also, the Darkling is an interesting concept of evil...he wants something good but is really going about it the wrong way. So he's the bad guy, but there are some things that you want to give him credit for... I love the love story between Mal and Alina and then way it played out was wonderful. I was completely emotionally involved. The plot was amazing and the pacing was good too...I couldn't put the book down. Read it all in one day. And, the best part, the writing was perfect! The one thing that always kills young adult fantasy is terrible writing, stilted dialogue. But the author nailed it with this book. SO excited to read the next one!
