Saint Peter's Wolf — Michael Cadnum

Art collector Benjamin Byrd has added a curious and most startling artifact to his collection: a set of fangs embedded in silver. He is mesmerized by his latest treasure, obsessed with looking at the fangs, holding them. Feeling their strange power.

Then the dreams begin. Dreams of prowling the darkness, of pouncing, of devouring. When he awakens, he is lying on the ground, naked and exhilarated.

Soon Byrd's transformation accelerates beyond his wildest imaginings. He tells no one -- not even his lover, Johanna -- of the nights when he runs free, the bloodlust pounding in his veins, savagely stalking his human prey in a world that seeks his destruction. But Johanna has secretes of her own, shocking secrets even he cannot escape.
