One moment magic dominates, and cars stall and guns fail. The next, technology takes over and the defensive spells no longer protect your house from monsters. Here skyscrapers topple under onslaught of magic; werebears and werehyenas prowl through the ruined streets; and the Masters of the Dead, necromancers driven by their thirst of knowledge and wealth, pilot blood-crazed vampires with their minds. In this world lives Kate Daniels. Kate likes her sword a little too much and has a hard time controlling her mouth. The magic in her blood makes her a target, and she spent most of her life hiding in plain sight. But when Kate’s guardian is murdered, she must choose to do nothing and remain safe or to pursue his preternatural killer. Hiding is easy, but the right choice is rarely easy . . . - goodreads.com
If you're looking for a series with a kick-ass heroine, this is it. Kate Daniels is such an awesome character that you can't help rooting for her. The supporting characters are interesting as well, with a mix of shapeshifters (the standard wolves, lions, tigers (even a vegetarian one LOL), bears? And even hyenas? LOL), vampires (none of that sparkling nonsense here), demons and of course, normal human beings (though they seem to be limited in numbers).
Most of the series focus on Kate battling a huge life-threatening, world-destroying challenges. Save the world before it ends prematurely and all that jazz. But there are also running threads throughout the series e.g. Kate's mysterious father and her relationship with Curran (heh it's hard to write about a series without giving something away :P)
I love the fact that the world Andrews created have magic and technology in an unpredictable relationship. Magic and tech battle for dominance, with magic surges rendering most technology obsolete and when it wanes, most of the spells are useless. The unpredictability lends an additional level of complexity towards the plot and created a more interesting twist to the phrase "urban fantasy".
Ilona Andrews is actually the pseudonym for the husband and wife writing pair, Ilona and Gordon. That's probably the secret behind why even though the story was written from the female POV, it maintains enough badass element to not be considered a "girly" series. In fact, this is probably my second favourite writer pair - the first being David & Leigh Eddings. (My introduction to the fantasy genre was through The Redemption of Althalus by Eddings. And I was hooked from then on LOL.)
I can't wait to see how this series progresses and what will happen when Kate finally meets her father. In the meantime, I am going to check out another series written by Andrews, The Edge.
