Fran has come back to face her ghosts: the fears she buried four long years ago. If she confronts them now she'll know they were only in her mind. Spring, in sunny Oxford, seems to light the way ahead. But on Salisbury Plain, she meets a living shadow - and finds that she is destined for a darker road.
Martin is still challenging his demons: phantoms he's glimpsed and cannot forget. Before his eyes they swarmed out of a medieval star-chart then vanished into the night without trace. Unwittingly, he has unleashed the Ravensbreed - an ancient sect of ruthless warriors pledged to protect the kingdom in its darkest hour. When the Ravensbreed are summoned, their enemies soon follow. And they all want to meet him.
Now, as hordes of undead stalk England's desolate landscape, hell-bent on creating a new era of darkness and fear, Fran and Martin must join the Ravensbreed in their final, desperate war: a long and bloody struggle which, if lost, will plunge the land into a brutal New Dark Age.
