Love! Even though this was a novella (which doesn't always work for me or many readers), this book was great - in fact, my only disappointment is that it wasn't a full length novel. I could read a full length novel with Derek. I could read a full length novel with Julie. I beg that they make a full length novel with both in the way of Gunmetal Magic.
Even though this is told from Derek's perspective (and we get a little glimpse into how broken he is), the real kicker is the foreshadowing for coming Kate Daniels books around Julie's building power as a witch. Ilona Andrews is setting up some edge-of-your seat stuff and I cannot wait.
