'A fast-paced dystopian thriller' - SFX Magazine

'First-rate science fiction' - Cory Doctorow

'As much a novel of ideas as it is a techno-thriller . . . A more erudite and emotionally engaging Philip K Dick' - Irish Times

In a familiar yet different Europe governed by AI, life is more efficient, objective, and peaceful. Yet all is not as it seems. Meanwhile, at Europe's eastern edge, the Federation endures under the rule of a President who has preserved his power by transferring his consciousness from body to body.

As both worlds begin to crumble, Lilia, a Federation scientist, discovers a way to slip the nets of surveillance and alter the balance of power. On the run, she becomes the reluctant centre of a struggle between resistance and control. Yet the systems and people surrounding her may already be beyond redemption. Is there any way to put humanity's future back in its own hands?
