It’s been 12 years since social worker Cassie discovered a mysterious mould in her home, invisible to almost everyone except her. Now the fungus has spread - its glowing spores a major global health threat, infecting the brains of those who inhale them. But many refuse to take seriously a menace they cannot see.

In Greek mythology, Cassandra was condemned to speak the truth yet never be believed. A story of trust and what happens when we lose it. And of a hidden threat destroying the very thing that makes us powerful.

A psychological horror story set amid the mysterious world of mycelium.

Mars, 2048. The first settlers, a mix of international workers and the super-rich. And the first unexplained death.

When a body turns up in the corridor between a scrappy warehouse and a half-built luxury hotel, no-nonsense Harbourmaster Rita Siddiqui finds herself in charge. With Earth temporarily out of contact and no official law enforcement on Mars, she ropes in Vice Captain Jaz Hickson, a wide-eyed young pilot who’s only just landed.

But murder's not their only problem. Atmospheric tests have triggered a dangerous storm. Paranoia grows as the power fails. Lights, gravity, oxygen: everything is at risk.

Rita and Jaz must navigate a growing list of suspects, a dwindling supply of patience, and a killer who’s not finished yet.

Because even 140 million miles from Earth, people still have secrets. And someone’s willing to kill to keep them.

With the hub evacuated, Rita and Jaz are alone. Can they find the murderer in time?
