Tommy is a normal boy, living a normal life, until he is ’called’. Along with his friend Lola, they travel to a distant land using a mirror which has ’called’ generations of his family, including his missing father, to become the Knight of Hunsbury Hollow. It is a kingdom of elves ruled by the weakening King Arrand and protected by a fierce dragon called Mercey. Together they are sent on a quest to defeat the Garracks, the creatures surrounding Hunsbury Hollow, and bring Prince Lorry back to the kingdom to reign as king. But what Tommy finds out along the way will change him forever
