Scare City by Paul Jenkins
Scare City is the hub where all of the world's ghouls, ghosts and goblins dwell in perfect harmony. It took the monsters centuries to overcome their differences and develop a realm in which they could live together in peace, but when a mysterious light begins to steal people in the night, paranoia takes hold, revitalizing ancient tensions between clans and causing Scare City to fall back into the hands of angry, pitchfork-wielding mobs! Its fate rests in the hands of a compassionate zombie-witch baker, Gina, who doesn't want to see her home be torn apart by hate, and is willing to do whatever it takes to bring everyone together once again.
