Mars, 2240. Beneath Olympus Mons, something older than human civilization has been managing a planet's atmosphere for two million years — and it has decided that terraforming is contamination.
Xenoarchaeologist Kessa Okafor drills two kilometers into ancient basalt and finds a chamber that should not exist: an alien megastructure, intact, awake, and watching. Her corporate masters call it speculation. The Marsborn — the first humans born to the red world, who breathe its thin air without help — call it the Gardener, and they have been listening to it for years.
As the seven-year terraforming threshold approaches and a fleet of fifty thousand refugees waits in dying orbit for permission to land, three incompatible futures collide. There is the world Earth wants to build, the world the Gardener will defend, and the world the Marsborn already are. None of them can have Mars whole.
Terraform Protocol is a planetary-romance trilogy about hubris and adaptation, about parent worlds and child worlds, and about the terrible cost of finally learning to coexist with something truly alien.
Terraform Protocol unfolds across three volumes on Mars between 2240 and 2260. Red Soil Rising is first contact buried in stone; The Architects' Warning is catastrophic misunderstanding; Two Worlds Burning is sacrifice and coexistence.
The setting is creeping dread beneath colonial optimism. The beauty of the Martian landscape — rust-red skies fading to butterscotch, light too dim and air too thin for unaltered lungs — contrasts with the wrongness of the changes humanity insists on making to it.
This is a first-contact story in which the aliens are long dead, but the machine they left behind still works, still maintains, and must finally judge whether humanity can share a living world or will always seek to remake it in its own image.
