Jennifer Marie Brissett’s 2021 Destroyer of Light is a stand-alone science fiction novel.
Centuries earlier the trans-dimensional krestge decided that humans were potential dangers too alarming to tolerate. They methodically exterminated humanity on Earth. Humans could not resist. A few humans, a mere remnant of the pre-genocide population, was permitted to settle on a distant, tide-locked world that humans called Eleusis.
Conceived on Earth, Cora does not remember the lost home of humanity. It is a shame, therefore, that the only world she has known is such a nightmare.
