To understand where he came from, one human boy must first uncover 66 million years of secrets.
Dinosaurs didn't go extinct. They fled. They evolved.
On Theia, Earth's hidden sister planet, they became Saurs: a civilization built on 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. 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 toward the truth of his origins. What waits there is a fierce girl, an egomaniac genius, and the twisted link between them.
With two worlds closing in, Filo must decide how far he'll go for the only one in the universe who ever chose him.
Saur combines the found-family heart and humor of Guardians of the Galaxy with the prehistoric intrigue of Jurassic Park in a young adult sci-fi adventure.
