Blue Diablo by Ann Aguirre.  Awesome book.  I want more.

Blurb

Right now, I’m a redhead. I’ve been blonde and brunette as the situation requires, though an unscheduled color change usually means relocating in the middle of the night. So far, I’m doing well here. Nobody knows what I’m running from. And I’d like to keep it that way…

Eighteen months ago, Corine Solomon crossed the border to Mexico City, fleeing her past, her lover, and her “gift”. Corine, a handler, can touch something and know its history—and sometimes, its future. Using her ability, she can find the missing—and that’s why people never stop trying to find her. People like her ex, Chance…

Chance, whose uncanny luck has led him to her doorstep, needs her help. Someone dear to them both has gone missing in Laredo, Texas, and the only hope of finding her is through Corine’s gift. But their search may prove dangerous as the trail leads them into a strange dark world of demons and sorcerers, ghosts and witchcraft, zombies—and black magic…

The bad news is…I have to wait until April for more.
