ultra-cute vampire half-daughter Alvina, Dan faces an unnatural caseload. Entire neighborhoods in the Quarter have simply vanished into thin air. Rogue werewolf cop Hairy Harry struggles to write and market his memoir. Customer complaints turn monstrous over an auto-mechanic shop run by gremlins, to whom "repair" is a foreign concept. And when unnatural doppelgangers appear in the shadowed streets, it does not mean double the fun. Entangled in it all is the mousy virgin librarian-now turned superstar celebrity-whose blood sacrifice, through an accidental paper cut, brought back all the monsters thirteen years ago. That anniversary is indeed an unlucky number.
