Late one evening, en route to visit a relative, an accident leaves Tory - the attractive, twenty-something daughter of a prominent history professor - stranded near a ring of stones in Britain. Tory resolves to spend the night at the stone circle and seek help in the morning. But across the vortex of time and space, she is taken back to the Dark Age. There she meets Prince Maelgwn of Gwynedd and his band of warriors. Initially her 'strange' appearance frightens them and they believe she is the notorious witch fabled to frequent the site. But she overcomes their fear and soon the tales of her adventures, brave deeds and beauty spread across the land.
