Autumn Moon is an acupuncturist and herbalist. When Jairec confronts her demanding she give him the elixir of life, she believes he's heard one too many Chinese legends about the Moon Festival. The chiang-shih of legends is a white haired, green-faced vampire—nothing like Jairec with his Irish good looks and charming manners.

When a mysterious attack leaves the victim drained of blood, Autumn is forced to believe monsters really do exist. She searches her uncle's journals. She must find a cure for Jairec. Time is running out.

Jairec and Autumn join forces to stop the master chiang-shih from raising an army and taking over Chinatown. Jairec will do all he can to keep Autumn safe, even if it means his death.
