Love at Stake by Victoria Davies
Abbey is the lone human working for Fated Match, a company that pairs members of the supernatural community with their eternal mates. To snag a young vampire socialite as her next client, Abbey journeys to the home of Lucian Redgrave, the most respected vampire on the East Coast. But he's not willing to recommend the agency to the vampire world... unless Abbey can first find his perfect match in a month.
As Abbey coaches Lucian through his dates, she can't deny the chemistry between them. But humans are toys for vampires, and risking her heart isn't a part of the plan.
