Will raw magic be their doom . . . or their saviour?

Jude is living happily with Moorley, Uncle Runie and Spry. But then the Dark Rivers start failing and raw magic is everywhere. The Consortium jumps into action and assures everyone that the situation is under control, but the people they are arresting are never seen again. And anyway, Jude knows better than to trust those in power. Jude and Moorley must find a way to reverse the effects of the raw magic. All their usual leads are sending them to dead ends, until Jude meets a strange boy called Darcius who seems to know far more than he should . . .
Can they resist the temptation of raw magic and save Farrowfell once and for all?
