Twilight Forever Rising by Lena Meydan

"Darel Ericson of the Dahanavar clan is a rarity among his vampire brethren: he’s an empath, strong enough to occasionally read thought as well as emotion.  For centuries, his power has given the Dahanavar a significant advantage against the machinations of the other vampire families, an advantage which makes Darel both a powerful tool and a highly visible target.

Fortunately for Darel, it is more useful for the heads of the other clans to maintain the centuries-long peace between the houses than to remove him.  But, the cunning and violent head of the House of Nachterret is tired of the truce, and of hiding his presence in the world.  The Nachterret would like nothing more than have free reign over the helpless human cattle upon which they feed.

Darel, and the human woman he loves, become central to the Nachterret’s scheme to plunge the Houses into all out war.  Darel is ultimately forced to face the question: is one young woman’s life too high a price to pay for peace?" (from Amazon.com)
