Psychologist Kris Marlowe doesn't believe in vampires, until a silver-tongued rogue rises out of a coffin at dusk, introduces himself as Sir John Falstaff, and hypnotizes her into letting him taste her blood. Kris's best friend Vi, who writes vampire romances, jumps at the chance to interview a real vampire. Fellow psychologist and paranormal cult expert Bram von Helsing also would love to meet an actual vampire. Kris remains skeptical, thinking she's just encountered one of San Francisco's many sanity-challenged individuals. Then in an attack of spine-tingling horror a horde of murderous monsters descend on the San Francisco neighborhood. Faced with creatures that kill with a single glance, Kris and everyone she cares about must fight for their lives. But how? In this dark fantasy with urban paranormal attitude, the only chance of survival for Kris and her friends is to seek help from the biggest bad boy in tavern-haunting history, who once drank ale and now drinks only blood—Sir John Falstaff, undead and misbehaving in San Francisco.
