Chicanery Road (Red Dirt Rune Chronicles #1)
Rachel Blake, Amilia Quinn

As sheriff, I live by a code of honor. A code that doesn't include defiling my little sister's best friend, no matter how badly I may want to.
But then the bodies start piling up, turning my small town into a graveyard for a madman. And Trixie, the girl I'm not supposed to want, disappears.
Screw the code.
Trixie is mine, and there is nothing I won't do — no rule or law I won't break — to get her back.
Even as I fight to save my girl, I’m forced to face a horrible truth: Evil has come to Theophilus. And we may not be strong enough to defeat it.
