From the author of the much-loved series Boudica and Rome, and the Sunday Times bestseller A Treachery of Spies, comes the visionary novel of a lifetime.
Sometimes it takes a revolution to change the world, sometimes it takes a relationship.
When Lan, anthropologist and grandmother, lies dying, she makes a promise that binds her long into the Beyond.

For one shining fragment of time, the world is with her granddaughter.

Watching over the growing chaos is Lan, who taught her family to think independently, approach power sceptically and dream with clear intent. She knows that more than one generation's hopes are on the line. It is only with courage and conviction, grounded in an ancient wisdom, that this digital uprising will survive and grow into what she knows it can be: a human movement, capable of profound change, that can sweep us all to a future that works before it is too late.
But Lan is dead, her powers to influence the living are limited and the challenge her grandchildren face is mythic in scale ...
