The parallel-universe Hibernian Empire has risen to supreme power, with the help of applied Old World technology (Hero's steam engine, etc.) and new World natural resources (Brendan the navigator pre-empted Columbus by some five hundred years). Now the starship Aisling Gheal and its crew extend Oirish manifest destiny to outer space. Healer Nolan, an unbeliever in the priest-kings of Gor -- sorry, Hibernia -- finds himself pitted against the ultra-conservative Monsignor O'Riordan.
