this book was really good. this book picked up exactlly were the last book left off. this book was a slow to start but then i picked up. there will be some major changes in the group of Sentinels. some parts of this book i had to reread because of the history of the other world. the main character is making me mad. she starts off super confident in herself and now she is acting like a week little girl. i don't understand the switch in her. the second half of this book the pace picks up. all of the action happens in the second half of the book. there will be a major death that happens in this book. the ending will make you scream.i don't have much more that i can say about this book other than to add it to your read list.
