Keepers of Earth.

One hundred and fifty years ago, global warming brought humankind to the edge of extinction. In a desperate bid for survival, 4,000 genetically enhanced soldiers - the last slice of humanity - were sent to eight space stations.

To serve. To protect.

Then the Critamal arrived, uninvited. Waves of aliens now work to break through the Orbitos' defenses, the black-shelled creatures seeking to colonize the vacated and barren world.

War is their reality.

All Romy can do is fight alongside her knot and watch from the mocking midst of the stars as Earth rises and falls in the distance. She dreams of a different life - one free from the mark of death and the never-ending touch of loss.

Be careful what you wish for....

When a technical glitch during battle leaves Romy and the four other members of Knot 27 hurtling through orbit towards planet Earth, Romy knows they are dead one way or another.

If the crash doesn't kill them, post-global warming conditions will.

Yet days pass as Romy wanders injured and aimless through the bush. Alone. Every second, every day she continues to breathe disputes what they have been told.

As Romy desperately searches for her knot, she comes across a grey-eyed man - a mysterious and close-lipped presence she is not certain she can trust. Especially when he shouldn't even exist.

Secrets are unmasked.

A different version of Earth bursts to the surface.

Will Romy survive the betrayal and lies threatening to shatter her mind like glass?

Earth was ruined. Humankind destroyed. Or so they were told...
