In this digital age, there is still a place for knots, skimming stones and stories of incredible courage. The Dangerous Book for Boys by Conn Iggulden and Hal Iggulden recaptures Sunday afternoons, stimulates curiosity and makes for great father-son activities. The brothers Conn and Hal have put together a wonderful collection of all things that make being young or young at heart fun—building go-carts and electromagnets, identifying insects and spiders, and flying the world's best paper airplanes.
