Constellation Draco is the second book in the Birth of the Gods series. The Mayans left Mars 50 years ago to journey 47 light years across the galaxy to the CM Draconis solar system. On Hyksos, the third planet in this system, they establish a colony and begin receiving supplies from their starship, orbiting above. However, shuttle fuel soon runs out, leaving the colonists stranded. Downriver Hyksos tribesmen attack the colony, destroying the windmill generator. As a result, batteries eventually fail and the Mayans lose radio contact with their starship. After the attack, the Mayans find Achilles, a wounded Hyksos from the upriver village. He has been shot with an arrow by one of the downriver warriors. Khons Imhotep volunteers to return Achilles to his people. The Mayan colony is trying to build a relationship with the upriver tribe. At the village, Khons meets Athena, a pretty red-haired girl, and he is smitten. Later, when downriver Hyksos tribesmen slaughter Colonel Ra's patrol, Sergeant Abydos Smendes assumes command. He then begins a brutal campaign to destroy all of the native people. Athena escapes with Khons across the mountains. Above the planet, a meteor strikes the starship. Now the Mayans must pull the ship out of orbit or they will plunge to the surface of Hyksos.
