Dragon Magic - featuring The Tribe

Dragon Magic is a fantasy adventure book for young readers. 'The Tribe', is the nickname of a sister and three brothers who love action and adventure. Their lives are completely changed when they befriend a baby dragon they discover in the woods. His mother had laid her egg on earth for safety, with the intention of coming back for him.
When the Dragon Queen finds him with the children, she asks if they will keep an eye on him as it is not safe for her to take him back to their home planet. She weaves a spell of invisibility around him and gives them each a talisman so that they can still see him. These gifts also have a magic spell which enables them to instantly go to anywhere they wish, simply by just picturing it in their minds.
They find this good fun, until they make a silly mistake which takes them back in time to a medieval castle. There they meet an alchemist with ambitions in sorcery. He steals Michael's talisman, which traps them in the middle ages.
They need help to free them from the dungeon, and a different kind of magic to get them back home. During their time travel adventure they make a discovery which will assist the Dragon Queen in her quest to rid her home planet of a wicked wizard.
The Dragon Magic fantasy adventure is suitable for children age 7-12 or by even younger children as a bedtime story.
