Blood Virtue - The Searchers, #3

Samuel Seecombe hasn't been himself since a routine vampire hunt went horribly awry, and a trip to New York for an acquaintance's wedding might be just what he needs to move on. What he doesn't anticipate is meeting his beautiful vampire hunting counterpart in Violet Singer. Violet wants a change of scenery. News of a vampire infestation at the Canadian border has her packing her stake, mallet, and holy water to take care of her wanderlust and the bloodsuckers at the same time.
Samuel-a quiet, mysterious Englishman who can wield a stake like no one else-accompanying her is an unexpected gift. But Niagara Falls isn't just for lovers and newlyweds. Vampires are increasing their ranks, and Violet and Samuel may find themselves outnumbered before they can sort out their feelings for each other.
