"Old 5th to 9th grade sci-fi book about a 1950s family with a bomb shelter under the house. The kids invite friends for dinner when a bomb threat sends them all into the shelter. They are transported to a dystopian world or reality where women rule men like slaves. They are eventually transported back to Earth in time to warn the families of the pending disaster. I read this young persons book in 7th grade, 1968 or 1969. "
