The Dangerous Book for Boys
Already a best-seller in the U.K., Conn and Hal Iggulden's The Dangerous Book for Boys has been adapted in moderation for American youngsters (Cricket is gone, Rugby remains; Conkers are out, Navajo Code Talkers in). The book is a guide to all things "boy," serving as a reminder of "lore and technique that have not yet been completely lost to the digital age".
Available from Amazon for $15.
