The Synopsis

Saur

Sixty-six million years ago, dinosaurs didn’t go extinct. They fled.

On Theia, Earth’s hidden sister planet, they evolved into Saurs: a civilization centered around science, hierarchy, and genetic perfection. Humans are nothing more than an ancient threat — one the Saurs believe they left behind forever.

Until Filo.

For as long as he can remember, Filo — a human teenager — has lived in the shadows of Theia with Mai, the Saur who rescued him from the wreckage of a space shuttle as an infant. But when the life she built to protect his impossible existence is torn apart, he’s forced to run.

Aboard an autonomous spacecraft with unexpected allies, he follows a trail of encrypted clues to a dangerous place: Earth. What he finds there is more than the truth of his origins — it is a fierce girl, an egomaniac genius, and the twisted link between them.

The farther he travels, the closer he comes to uncovering what he truly is and just how much Mai sacrificed to save him. With two worlds closing in, Filo must decide how far he is willing to go for the only one in the universe who ever chose him.

Saur fuses the found-family heart and humor of Guardians of the Galaxy with the prehistoric intrigue of Jurassic Park, delivering a young adult sci-fi adventure layered with mystery, survival, and high-stakes discovery.

What is the Octomer?

The Octomer is the Saurs’ classified record of engineered traits, each drawn from a different prehistoric ancestor. Eight of them: sight that resolves movement about eighty kilometers out, gills that never need to surface, a tail-whip that breaks the sound barrier, a sprint of roughly a hundred kilometers an hour, a wingspan near six meters that stays aloft for days, hearing that reads footfalls at a similar range, a scent trail still followable days after it was laid, and an intellect decisively beyond human. A Saur is a dinosaur that never went extinct — one of the descendants that fled Earth sixty-six million years ago for Theia, its hidden sister planet, and evolved there into a civilization built on science, hierarchy, and genetic perfection. Filo, the human teenager at the center of Saur, grows up hidden in the shadows of that civilization.
