Trivia
The book title is a possible reference to the Fallout fan site, Duck and Cover.

More likely (and factual based off of the cover of the book showing people hiding under desk), the book may be based off of a late 1950's through 1960's short cold war propaganda film called "Duck and Cover", a film about a turtle named Bert, who would duck and cover during the sign of any danger.

The film was present to students in classroom's across the states to teach kids what to do in the event of a nuclear attack on the United States. The following video is a Fallout 3 based song with the Bert the turtle theme song played in the beginning, the same song that was placed to children attending school in the 1960's: 500px
