I thoroughly enjoyed this book, but I have to hand it to the book's narrator, Susan Duerden. I'd previously listened to another one of her narrations, [[ASIN:B00ANY7BAU Chime]], but this really was exemplary. She does a great job of not only imparting the tenseness, but also does an amazing job of capturing the male voices and the various accents. Partway through this audiobook I kept thinking that I almost wish that I'd bought this rather than renting it from the library, as I'd love to listen to her read this again. Her narration is that good. I could go on for hours about how amazing she is, but I'll just stop short and say that you really haven't fully experienced the book until you've heard her read it. 
 Story-wise, this was a really great debut novel. There are a few points to it that I winced at. I found it a little far-fetched that nobody would raise an eyebrow at Myfanwy's new behaviors, especially considering that there was a fear of people getting into the organization's top tiers. Nobody ever questions that Myfanwy might have been compromised in some fashion, partially because she's now so good with her powers? A little hard to believe. I enjoyed the book so I didn't question this that much, but it's something that I know others will see as a bit of a plot hole. The ending was also a little rushed, but again- I overlooked this for the most part. These two elements were enough for me to remove a star, as the more I think about them the more I feel that they could have been smoothed out and resolved a little better. It just felt a little abrupt, as if the book was edited down or if O'Malley was told that he only had a certain amount of pages left in the book. 
 But like I said, this is a highly enjoyable book and I really can't wait for the second book to hit the shelves. Most of the bigger loose ends are tied up in this book, so if something awful happens and the second book never comes, at least we have an ending of sorts here. You can't help but like Myfanwy and some of the other characters in the book. 
 I thoroughly recommend reading this, especially considering that this has the makings of the next big Hollywood blockbuster. It really deserves more attention than it got when it came out, that's for certain.
