If you've been on the fence about the Hollows series, this book will bring you back to the series. I can't say anything without spoiling the book for you, but rest assured- this book was awesome. This has to be one of the best books in the series so far. It doesn't beat out the first book as my favorite Hollows read, but it's up there. 
 Where to begin? For starters, you'll love that even though not everything is resolved in this book, Harrison does her best to address many of the concerns & questions that fans have been having over the series. I won't state which ones get the most attention, but I opine (as Pierce would put it) that the many people will be satisfied in one way or another. 
 Also wonderful is the maturing of Rachel. She's still the type of person who is capable of insane feats of magic, but this Rachel is one who no longer sees things (as she puts it) in the "black and white" views as she did at the beginning of the series. This shows in many of her actions in this book & the decisions she makes during the course of her adventures in this book. 
 This is an awesome book & one that anyone following along with the Hollows series NEEDS to read. Not breeze through in the store or library, but read. This was just sheer awesomeness & I really feel like I can't say enough good things about it. I loved this book.
