Keith D'Ameron has wandered the world as a vampire for three hundred years and until now, he has simply enjoyed what his world of the night can bring to him, but upon entering Seville, a heartbeat rises above the rest of the thrumming pulses occupying the busy city, and something in its siren call urges Keith to investigate.
The owner of this heartbeat is a beautiful young man named Javier Estas, and upon first sight, Keith knows he must make the young man his own. Something in the scent of his blood, and the very thrum of the life in Javier's verdant gaze, has drawn Keith to this man, and he is determined to find out why. Something within Javier's eyes calls to him as nothing else has ever done, and Keith soon finds himself hopelessly in love.
At first, Javier is hesitant, but Keith is not the only one lured by their incomprehensible connection, and he finds himself captivated by the glimpses of Keith's world he sees every time he falls into the vampire's eyes. At last, he finds that he cannot continue to deny his undisclosed desire for Keith - and that he doesn't want to keep trying.
