Jim Butcher's The Dresden Files: Ghoul Goblin

Harry Dresden came to rural Boone Mill, Missouri to free the star-crossed Talbot family from the curse that's nearly wiped out the bloodline. Unfortunately, his only two allies have been fired from the local police force and revealed as a carnivorous ghoul, respectively-oh, and he's been arrested, leaving the aforementioned Talbots virtually defenseless against the supernatural creatures hunting them. Aside from that, things are great.
