Book excerpt: Maureen "Muffy" Birnbaum is a young woman swept away from prep school to partake in a series of adventures in locations that seem extremely strange to her, but are readily familiar to science fiction fans. Muffy has visited Barsoom, Sherwood Forest, the Moon, and many other fantastic venues. She doesn't mind being sent to these outlandish worlds, because she usually meets a really cute boy while she's there.
