Spirit Hunters dwell secretly among us, their existence hinted only in legend and flashes of intuition: chills along the spine; disturbing, elusive dreams. They are our kin. They are vampires. They are dying out. To live, they must drink the essence that quickens human blood. Now, to survive, they must befriend their only prey. Lilith longs for her people to endure. A brilliant, beautiful biologist, she believes she is the last of her kind, and so becomes entangled with human scientists in San Francisco in a quest to extend her own life and reproduce asexually. Meanwhile, high in the Himalayas, Jared searches for a reason to live or to die. Old monks of startling powers offer him their blood, and a chance to restore his people. Shadowing them all, an ancient, powerful spirit hunter believes that his kind must be destroyed, and has a plan to accomplish it. On the edge of extinction, the arcs of their journeys converge. Their only hope lies in dangerous, enticing intimacy with their only prey. Rapt with fear, love, and wonder, Spirit Hunters and humans reach across a seemingly unbridgeable chasm to confront a timeless, urgent question: Who shall live?
