When Dan and Ursula become lost in a thick mist, they have no idea that once they step out of the other side they will find themselves in an England of thousands of years ago and embroiled in a civil war between ancient Britons and Romans. Soon they will have to rely on strengths that neither of them knew they had as they battle both physical and magical enemies, not only to ensure their own safety, but also to try and help save the lives of the Combrogi who face the might and power of the Roman army. In this powerful and sweeping epic novel, survival depends on learning magical arts and respecting codes of behaviour that pre-date all modern life. It is a difficult world to survive in. Are Dan and Ursula able to master all they need to know in time to ensure that they do not become victims of a time far harsher than any they could ever have imagined?
