On the edge - Ilona Andrews

Step into a whole new world in the first Novel of the Edge from the #1 New York Times bestselling author of the Kate Daniels series.

The Edge lies between worlds, on the border between the Broken, where people shop at Wal-Mart and magic is a fairy tale-and the Weird, where blueblood aristocrats rule, changelings roam, and the strength of your magic can change your destiny...

Rose Drayton thought if she practiced her magic, she could build a better life for herself. But things didn't turn out the way she'd planned, and now she works an off-the-books job in the Broken just to survive. Then Declan Camarine, a blueblood noble straight out of the deepest part of the Weird, comes into her life, determined to have Rose (and her power).

But when a flood of creatures hungry for magic invade the Edge, Declan and Rose must overcome their differences and work together to destroy them-or the beasts will devour the Edge and everyone in it...
