As Rome closes in on the last sanctuary of the Druids, a frightened novice is sent unwillingly across time, torn from ancient Britannia and cast into a world of machines, noise, and invisible powers. With only his wits, his old knowledge, and a toad for company, Ffôlkath must make sense of an age that mistakes progress for wisdom – and discover why he alone may stand between mankind and a new form of order.
