Dilynwyd Vern, menyw du ag albinedd, sy’n dianc sefydliad crefyddol yn Sorrowland. Tra mae hi’n wneud hyn, maent yn darganfod bod ei chorff yn newid, wrth iddi ddatblygu pwerau. Wedyn, rhoddwyd genedigaeth i efeilliaid, ond mae hi’n parhau i bryderu am ei chorff pan mae’n newid yn bellach…

Vern, a hunted woman alone in the woods, gives birth to twins and raises them away from the influence of the outside world. But something is wrong – not with them, but with her own body. It’s changing, it’s stronger, it’s not normal.

To understand her body’s metamorphosis, Vern must investigate the secluded religious compound from which she fled and the violent history of dehumanisation, medical experimentation and genocide that produced it. In the course of reclaiming her own darkness, Vern learns that monsters aren’t just individuals, but entire histories, systems and nations.
