A mysterious book of prophecies left by a sixth century Irish monk has baffled scholars through the ages. Foretelling wars, plagues and rebellions, it is said to have predicted the Black Death and the Gunpowder Plot. Some believe it foresees the Day of Judgement. But is it the result of divine inspiration or the ravings of a madman?

A hidden hoard of Saxon gold. A poisoned priest. A monk skinned alive in Westminster Abbey. Only one thing is certain: whoever comes into possession of the cursed book meets a gruesome and untimely end.
