In the Province of Britannia, ruled by descendants of King Arthur and on the brink of an industrial revolution, young Maia Abella is on the run.

Something unseen has murdered her cruel mistress and she's being blamed. The streets and factories of Portus are no place for a friendless girl, trapped in events beyond her control.

The city authorities and the Royal Navy are both desperate to find her - one investigating a killer, the other to recruit her, while the deadly legacy of a tragic past stalks her every step.

Aided by Raven, an ancient, blind Mage with a terrible secret and Milo, Crown Agent and spy, Maia must discover and overcome the fatal consequences of her birth.

Meanwhile, the Gods are making their moves. And not all of them are friendly.
