So, in a world where magic and technology are at odds, where either technology works or magic works, but never (or very rarely) both, enter Kate Daniels, badass mercenary and magic worker.

I'm really intrigued by the world building, but also a bit frustrated and curious at the same time. How does the switch between magic and tech work? Magic is integrated into the world and accepted, obviously, but what about other supernatural creatures? We only ever see one human come into contact with a supe, and his reaction is not enough to understand what the dynamics are. I'M JUST SO CURIOUS, I WANT TO KNOW.

Oh yeah, and there's Kate. Badass, sarcastic, keeps going even when she's hurt, etc etc, Strong Female Character.

She's cool, but I want to know more about the world. On to book two.
