I've read the second book in the series. Green-Eyed Envy picks up after the events of Red Hot Fury, although not directly. In this one Riss and Scott are tracking an arcane serial killer. I enjoyed the story even though it was slightly formulaic but I did get annoyed that Riss didn't put together several puzzle pieces that she should have much sooner. I knew who, how and why before the book was half over, so Mackenzie wouldn't be that great of a mystery writer. Fortunately, she wasn't really writing a mystery, more of an urban paranormal action thing. This book seemed to be more platform for setting up book three than a stand-alone story in its own right. Disappointing, but not enough to put me off reading book 3.
