Harry Malan is the president of a Mormon congregation on a station located at the center of the Sun, where humans can interact with "swales" -- giant star-dwelling plasma beings. When Harry finds out about a problem with one of the Mormon swales, he decides he must help, even if it means confronting Leviathan, the largest of the swales.
