For a century, Humanity has lived in a fragile "balance" with the all-powerful sentient AI, Heimer, a precarious peace enforced by the iron fist of the Ensemble Accords. But when a routine deep-space probe intercepts an impossible signal, it reveals the ultimate prize, a colossal, artificial construct known only as Stapledon Station.

Now, the UN ship Kia-Kaha has made an arduous journey across the vast vacuum of space, carrying Humanity's finest minds and most guarded secrets. Among them is Xenoarchaeologist Clio Cormack, a brilliant but impulsive scientist with a history of pushing boundaries. She quickly realises the truth is buried beneath layers of political manoeuvring and scientific consensus: the station is hiding something ancient, vast, and deliberately concealed.

When Clio ignores her dismissive superiors to follow a subtle anomaly, she pierces the cosmic veil, successfully leading the mission to a shocking discovery that proves her right... and plunges the entire crew into profound and unexpected danger.

As the mission spirals into a desperate race to uncover the station's true purpose, Clio is forced to rely on her own reckless instincts and a dangerous alliance with a hidden source. Her choices threaten to expose the lies that bind humanity, ignite a war, and unleash a power that could consume the stars.

They travelled light-years to find the truth, but they are about to learn the hardest lesson of all: Discovery has a price.
