The Hunter and the Hunted

Delilah Christos loves 3 things: her sister, old cars, and running.
She's gotten good at that last one. As a Bounty Hunter Delilah follows the money wherever it leads-Coven quarrels, toe-biting faeries, Heat maddened she-wolves-the farther and more perilous the job, the happier she is.
But the past has a habit of catching up. There's a murderer loose in Witchhill, a tiny town nestled in the Rocky Mountains, a town her sister, Athena, still calls home.
When someone places a bounty on the serial killer, Delilah must return to the place she fled almost three years ago. An Otherworlder on a killing spree she can handle, it's what they might be looking for that threatens to send her running; this time with Athena in tow.
