Avilion - Tapa dura

At the heart of Ryhope Wood, Steven and the mythago Guiwenneth live in the ruins of a Roman villa close to a haunted fortress from the Iron Age, from which Guiwenneth's myth arose. She is comfortable here, almost tied to the place, and Steven has long since abandoned all thought of returning to his own world. They have animals, protection and crops.
They also have two children, a combination of human and mythago. Jack is like his father, an active boy keen to know all about `the outer world'; Yssobel takes after her mother, even to her long auburn hair.
But this idyll cannot last. The hunters who protected Guiwenneth as a child have come to warn her she is in danger. Yssobel is dreaming increasingly of her Uncle Christian, Steven's brother, who disappeared into Lavondyss, and Jack wants to see 'the outer world' more than anything. Events are about to overtake them.
