Kate Daniels is a mercenary - a monster killer for hire - in a world in flux. Alternating waves of magic and techology began to wash over our world a few decades back and the magic is gradually winning out. In its wake a lot of the old nightmares from mythology have awoken.
As if her day job wasn't dangerous enough, Kate is hiding a secret that could get her killed - and the more she gets dragged into events the more likely that secret is to come out.
The Edge lies between worlds, on the border between the Broken, where people shop at Walmart and magic is a fairytale – and the Weird, where blueblood aristocrats rule, changelings roam, and the strength of your magic can change your destiny. Only Edgers, the people who live in that narrow in-between strip, can easily travel from one world to the next, but they never truly belong in either.
