Only Edgers like Rose can easily travel from one world to the next, but they never truly belong in either.Rose thought if she practiced her magic, she could build a better life for herself. But things didn’t turn out how she planned, and now she works a minimum wage, 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 her (and her power).But when a terrible danger invades the Edge from the Weird, a flood of creatures hungry for magic, Declan and Rose must work together to destroy them—or they’ll devour the Edge and everyone in it.

    She also happens to be a walker, a magical being with the power to shift into a coyote at will. Mercy's next-door neighbor is a werewolf. Her former boss is a gremlin. And she's fixing a bus for a vampire. This is the world of Mercy Thompson, one that looks a lot like ours but is populated by those things that go bump in the night. And Mercy's connection to those things is about to get her into some serious hot water...
