Nimuë Taylor thought working for a vampire would be cool. Instead it’s just like any other annoying job, complete with a boss, Colin, who drives her crazy. Other than the daily humdrum routine, nothing much exciting happens. Until the day Sebastian, Colin’s old friend (read: ex- lover) comes to town bearing a magical stone that can make any vampire immortal. Really immortal. He doesn't want to use it, just keep it out of the wrong hands. Trouble is, the wrong hands are getting far too close—and the stone is slowly draining Sebastian's life force.

When Nim unwittingly comes between the stone and its hunter, she's bitten. Not by just any vampire, but by one whose bite turns victims into mindless zombies. Healing her involves a ritual that creates a blood bond that's as passionate as it is dangerous. For in the fight to keep and destroy the stone of ultimate power, one of them will have to break that bond…and make the ultimate sacrifice.
