Not Frost's Best Work
First, don't buy this book unless you've read Frost's previous Night Huntress books--it does not stand alone (and I wonder if all these 4 and 5 star reviews are holdover feelings from Frost's previous novels). Second, if you have enjoyed Frost's previous books, you KNOW you're going to buy this one, but prepare to be disappointed--so, just suck it up, I guess.
Why I'm disappointed:
This book would have benefited from an extra 100 pages. The basics of the plot were there--woman with paranormal ability is in danger from a bad guy so she must turn to a somewhat less bad guy for help--but detail and dialogue were lacking. (Cat, Bones, Mencheres, and Kira make a brief, gratuitous visit, and as much as I like them, Frost could have used those pages for development of something else.)
There is a noticeable lack of detail concerning the backstory of Leila, the female lead, and considering the novel's told from her point of view that's a problem. For example, Leila's best friend, Marty, with whom she lives and works, is a vampire (convenient since she doesn't have to go through that whole vampire-revelation thing), but there's no real explanation of how she met him. And it's not an obvious relationship that doesn't need explaining. This lack of detail would be fine if Leila were a character like Denise (First Drop of Crimson) that Frost had introduced in prior books, but she's not. I have a hard time caring about Leila or believing her acceptance of her new life.
One of the things I loved about Frost's earlier Night Huntress series was the interaction between Cat and Bones. She talks, he talks, and there is a sense of their relationship developing over time--even in the first book. In this book, however, the timeline is only a matter of days which makes it hard for me to accept the interaction between Vlad, the male lead, and Leila. In fact, I don't think they actually spend that much time together--Vlad is away a lot. Also, Vlad has the ability to read Leila's mind. This little plot device didn't come up until at least a couple of books into the Night Huntress series, and in this novel it's downright annoying. It just feels like a cop out so that Vlad's character doesn't have to say much. In fact, there are several scenes where he just stares at Leila. This uneven ability would really hinder a developing relationship and the interaction between Leila and Vlad would be more interesting without this little twist.
Ultimately, it just seems like Frost is depending on her previous stories to make this novel work. There seems to be a lot of Frost winking at the reader as if to say, "You've already got this and I don't really need to develop it, right?" I'm sure I'll buy the next Night Prince novel (Vlad and Leila don't have a resolution and the next one is due out next spring), but I'll be hoping that Frost steps it back up.
