Where Merlin Rests: Myfanwy's People, Book Two

Volcanoes all over the Earth are erupting as the ‘dragons’ within the Earth are being stirred by magic. As the Earth faces the catastrophic possibility of an eruption of its super-volcanoes, a criminal gang is hunting Myfanwy and a monster stalks Tom. Together they must find Merlin, who alone can quieten the earth, and they must get to him before those trying to kill him. They also need to sort out their relationship as the end of school is approaching and Tom is returning to Australia.
