Once Bitten — Sara Reinke

Private investigator John Harker thinks he's seen it all. But when a desperate woman begs him to find her missing daughter, John quickly learns there are many things in the Florida Keys that are best left unseen...and some secrets that are best left undiscovered. In a dark spin on the screwball comedy formula, John is bitten by a vampire, doomed to become one of the bloodthirsty undead unless his beautiful, plucky assistant Sandy (whose real name, as she sometimes still bothers to remind him, is Maureen) and a renowned but reluctant anthropologist specializing in vampire legends and lore, can save him.
