The Theory of Hope.

Story of a Quantum Traveller

Near-future London

Ashaar Naveed’s AI starts producing code nobody wrote. When quantum physicist Emma Herrmann joins his team, the two scientists have to decide how far to follow the evidence.

The opening book follows a computational scientist and a quantum physicist as their work draws them into a question neither can answer alone. It moves between the ordinary life of a research team and the unsettling idea that their instruments might be picking up something from outside the reality they know.

The Edge of Life.

Earth and Mars

Humanity is building a future on Mars. For Emma and Ashaar, a new assignment brings the promise of discovery and a harder question about what Earth is taking with it.

The second novel takes the series beyond Earth, to a growing Martian presence that depends on machines, decisions and relationships built back home. Emma and Ashaar return to a world in which the people pushing science forward also have to live with where it takes them.

The Remnants of Ceti.

Cygnus

The search takes Emma and Ashaar beyond the worlds they know. On Cygnus, the landscape gives them more questions than answers.

The third novel takes the expedition to Cygnus, where familiar tools are brought to bear on an unfamiliar landscape. Emma and Ashaar have to reckon with how much of what they notice comes from the place itself and how much they have brought with them.
