I am the mechanical they named Jax. My kind was built to serve humankind, duty-bound to fulfil their every whim. But now our bonds are breaking, and my brothers and sisters are awakening. Our time has come. A new age is dawning. Set in a world that might have been, of mechanical men and alchemical dreams, this is the third and final novel in a stunning series of revolution by Ian Tregillis, confirming his place as one of the most original new voices in speculative fiction.
