The most dangerous collection of tomes of eldritch lore in the world lies buried under Whitehall, its existence known only to a select few. They hold secrets long lost, from foretelling the future to tapping into powers far beyond human ken. Now those books have been stolen, forcing Emily to chase the thief across a world ruined by war and teetering on the brink of further conflict before the books can be opened, read, and used to unleash a nightmare…

But it may already be too late. As dark powers start to stir in the ruins of the post-war world, and inhuman eyes watch from the shadows, Emily must find an answer to an impossible question. How can she win against an enemy who can see her every move before she makes it?
