Now Georgina is playing referee between a ghost and her angry grandmother, while trying to manage the handsome, rugged sheriff Ash Barrett, who constantly teases her for her stuck-up Easternly ways. Problem is, no matter how desirable Ash finds Georgina, he's dead set against marriage. But with Devlin's haunting help, Ash Barrett just might see the error of his ways, before he loses life's most precious gift...
