Day Shift, by Charlaine Harris

The first in a new series by Charlaine Harris, so the plot is slim while CH establishes the rules governing her world, Midnight, TX, and introduces her cast of supernatural characters: psychic, Manfred Benardo; vampire, Lemuel; woman of mystery, Olivia Charity; witch, Fiji; and Bobo and a number of other Midnight residents who might be something not as easily defined.
