After founding a colony on the remote moon of Freyja, the missionary order of Assumptors resumes searching for a new Earth. Yet its recently elected leader, Mother Josephine, faces unforeseen challenges. An uncooperative council. An impulsive Helmsman. And a Navigator bent on fulfilling his own quest as he directs the ship towards an enigmatic star. Back on Freyja, Father Chadwick and his settlers face trouble. Strange noises disturb them at night. They grow afraid of the forest. One by one, people disappear... In a space mission driven by deceit and ambition, nothing is as it seems. Will Mother succeed where her predecessor failed? Will Chadwick regain his sense of purpose? Sun God is the second book in the Assumptor space opera trilogy, continuing the voyage that began in Brightest Star.
