In this long-awaited sequel, written with his sons Cameron and Arthur, Conn Iggulden presents a brand-new compendium of cunning schemes, projects, tricks, games and tales of extraordinary courage. Whether it’s building a flying machine (keep your temper with this one) or learning how to pick a padlock (for your own shed door - not someone else’s), discovering forgotten explorers and the world’s greatest speeches, or mastering the fiendish task of solving a Rubik’s cube, this is the book to turn boys into danger men.
