Rick Newlands has written a 2nd edition of his book entitled 'Rocket Science and Spaceflight for young Rocketeers' which is a guide to home-built rocketry and home-built spacecraft for ages 14 and upwards (though a smart 12-year-old could understand the first half of the book). The final chapters are an advanced section for young and old rocketeers who really want to know, and include full instructions for designing, constructing, and testing nitrous hybrid rocket engines.
