" Passion filled him, terrible and sweet, a craving as fierce as ever. It was not something one could turn on a courtesan-this wantom cupidity-and expect him to live. But another wampyr was not prey, was not a courtesan. Another wampyr was an equal and a rival, though David might be less than a quarter Sebastien’s age, and quite capable of surviving his unalloyed strength. "
