"I think we've come through the period when we said boys and girls were exactly the same, because they're not. Boys and girls have different interests, different ways of learning, and there's no real problem in writing a book that plays to that, and says, let's celebrate it. Let's go for a book that will appeal to boys."
Exuding the brisk breeziness of Boy Scout manuals and Boy's Own annuals, "The Dangerous Book" is a childhood how-to guide that covers everything from paper airplanes to go-carts, skipping stones to skinning a rabbit.
"I wanted to do the kind of book that we had lusted after when we were kids," said Conn Iggulden, who co-wrote the book with his younger brother Hal.
He and Hal, a theater director, researched the "Dangerous Book" over six months in a garden shed, rediscovering the lost childhood arts of secret codes and water bombs and building simple batteries and pinhole projectors.
