Stone yard devotional

Burnt out and in need of retreat, a middle-aged woman leaves Sydney to return to the place she grew up, finding solace in a small religious community hidden away on the stark plains of the Australian outback. But disquiet interrupts this secluded life with three visitations. First comes a terrible mouse plague, each day signalling a new battle against the rising infestation. Second is the return of the skeletal remains of a sister who disappeared decades before, presumed murdered.
And finally, a troubling visitor plunges the narrator further back into her past.
