Domum is set in a world torn in two, with Musod's leadership focussed on ever increasing consumption, while the Domum people are determined to save the planet from their dawning expectation of a 6th extinction. Our heroine is a young woman, Sophia, guided by an invisible Voice, who has taken on the spiritual leadership of Domum; but what follows is not just the invasion of Domum by Musod, which is eventually repelled after several close-run battles, but also her own struggle between her passion for her intangible Voice, and her carnal love for her actual partner Mark.
