Oh my gosh is was so good. This book reminded me how fast I can read a nearly 400 page book. Usually it takes me a week, not 2 maybe 3 days. I just didn't want to put it down. 
 Sometimes I feel like Arthur is upping the anti on Riley. Making things harder, more diabolical. But really I think it felt that way because while the crimes she investigates in this book are horrifying they aren't as bad as the last book, but you wouldn't know by reading it. Everything just flows. She's got to find a guy who is killing his ex-classmates and who seems like a vamp but can't possibly be. And then there is the cat thing that she thought might be a shifter but turns out isn't and is killing everyone who it thinks wronged her previous owner. I mean it's really exciting. Poor Riley doesn't get much of a break. 
 Remember all the characters Arthur has dragged into this story? Kade, the horse shifter. Riley's brother Rhoan. Liander Rhoan's soulmate. Dia the blind woman who seems to be able to see and tell the future. Dia's daughter which Riley saved in the last book. My theory was she couldn't possibly update you on all these people without stepping outside the story. I was sooo wrong. 
 We get great flow-ins of Rhoan and Liander. Dia helps out a bit and you get to see her daughter who is totally cute. Kade is Riley's partner so you get to see him too. Everything flowed so well and the story was exciting. There is even that moment when you are terrified and on the edge of you seat because of the books description... (Riley knows she's got the skill and cunning to catch two serial killers at once...until one of them strikes inside her own tight-knit clan). I guessed what this meant but wasn't sure what would happen because there seems to be all kinds of foreshadowing. I'm so glad I chucked me reading list for this book! 
 Oh hey and remember the whole Quinn and Kellen thing. Poor Riley getting her heart shredded by Kellen. She is so much more reserved because of it. Afraid to put herself out there which makes for a nearly smutless book... and funny thing... it didn't bother me. I still highly enjoyed it. 
 Remember the stripper Ben? Well he owned the stripper company. I think it was in the last book. I vaguely remember him but he's in this book cause his friend got attacked. He hits on Riley, but she's not ready for more heartache. He tells her he lost his soulmate. I was stunned because my impression was that they couldn't live without one another. Of course, this is Riley's impression too. But he asks what she felt with Kellen and makes her realize he wasn't her soulmate because she wouldn't be able to live without him. He explains how he managed. 
 And then Quinn. Damn, but that Vamp oozes yumminess. This 1200 year Vamp has had his issues and through it all I have still wanted to call him my own. hehehe. So he tried to control Riley and she dumped him. Good for her. Only he's been hurting just as much as she so when they see each other... sparks. Major sparks. Gotta love it. And after Ben's description of soulmates... makes you wonder about Quinn. 
 So I say if you like Vamps/Werewolves, this is an awesome series and book!
