The Face of God is what every young saurian learns to call the immense, glowing object which fills the night sky on the far side of the world. Young Afsan is privileged, called to the distant Capital City to apprentice with Saleed the court astrologer. But when the time comes for Afsan to make his coming-of-age pilgrimage, to gaze upon the Face of God, his world is changed forever- for what he sees will test his faith...and may save his world from disaster!
This book is the first in the Quintaglio Ascension trilogy. While there are certainly liberties taken by anthropomorphising dinosaurs, for the time this was written the dinosaurs are referenced with decent accuracy.
Also of note is how the dinosaurs are referenced in the book, such as 'armorback' and 'shovelmouth' referring to Ankylosaurus and Parasaurolophus.
