This wasn't my favorite of the series. I had a hard time concentrating on it & I found it to be slow. It wasn't till the last 75% I got somewhat invested into Dev & Katya. I did enjoy the ending and how everything played out. We did learn a wee little more about the Arrow's and some of the other Psy kids that are living with the Dark River pack so I liked that too. Even though it took me forever to read, I'm glad I still did (I almost skipped this book) because I did get more insight on what's going on & what may happen.
