On the Edge by Ilona Andrews

Brand new but there are some imperfections as shown.

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...
