Slayer:
"It's 1946, and Colonel John "Renny" Renwick is called in to build the new high school in Sunnydale, California. His brilliant engineering skills are needed to overcome "structural anomalies" which have brought construction to a halt, but the two-fisted engineer is soon fighting for his life against the forces of darkness. While Doc Savage and the rest of his Iron Crew struggle to reach their embattled friend, Renny's only hope of survival is a blonde-haired little slip of a girl named Buffy, who claims she's a vampire slayer from the future."
