To mortals, anyway.

Voss felt oddly prickly tonight, as if something irregular were about to happen.

Perhaps it was simply that he’d not been out in London Society for years, although he would never ascribe his unsettled feeling to nerves. A one-hundred-forty-eight-year-old vampire simply didn’t have nervous energy…even when he came face-to-face with his own weakness, which, in the case of Voss, was the unassuming hyssop plant.

Each of them, each Dracule, had a personal Asthenia—an Achilles’ heel or vulnerability, or whatever one wanted to call it. Other than a wooden stake to the heart, a blade bent on severing head from body or full sunlight, the Asthenia was the only real threat to a member of the Draculia. And even then, the Asthenia caused only pain and great weakness—which often allowed for the stake, sword or sun to do its business.

Not that the Dracule ever discussed or even disclosed this frailty. It was a personal thing, akin to having a flaccid member at the most inopportune moments. Never spoken of, never acknowledged, never dissected. There was, as Giordan Cale had once said, honor among thieves, pirates and the Draculia.

Yet, in an attempt to keep his mind occupied and in a bid for personal amusement as well as leverage in the event he needed it, Voss had made a sort of game of it to determine the Asthenias of his Draculian brothers. He considered it nothing more than each man’s unique puzzle, and by craft, cunning or mere observation, he had determined the weaknesses of many of his associates.

It was nothing he hadn’t been doing for years, for Voss had long been a trained observer. He’d grown up the youngest child and long-awaited heir, and he spent much of his youth eluding tutors and spying on his five elder sisters.
