The only cure for a deadly plague sweeping the country is the crystal fang of a dragon that has terrorised the surrounding countryside for many years. Until now, the location of its den on Dragon Ridge Mountain has remained a mystery. In a race against time, Jack battles through a storm to reach the top of Dragon Ridge Mountain. With Merlin to guide him, Jack enters the dragon's den and comes face to face with the monstrous beast. This is a story of courage, magic and one boy's brave quest to fulfil a destiny foretold by the legends of long ago.

Join Jack on his journey as he writes the story with the assistance of the magician Merlin and Punctua, the Fairy Godmother of Writing, to punctuate properly and become a bestselling author.
