Fair warning, there is a cliffhanger! I've read the Darkest Powers trilogy by Kelley Armstrong, and this is sort of a spin-off. The progression of the plot was nicely paced in this book. I didn't want to put it down towards the end. It kept me asking questions the entire time. I can't really give anything else away other than what the synopses tell you without spoiling the entire book. I'm very interested in reading more. I have questions that need to be addressed. I do think I like this better than the Darkest Powers so far. I would give this a 3.5
