The Egg — M.P. Robertson

When the eggs hatches, and a baby dragon comes out, George knows exactly what to do.  A baby dragon needs to learn how dragons are supposed to act, including how to fly, how to breathe fire, and how to defeat a knight-so George starts the dragon lessons right away!  The dragon learns quickly, but he is anxious to find his own kind.  Then George wakes up the next morning and the little dragon is missing.  Will George ever see his dragon again?
