Burnt out and in need of retreat, a middle-aged woman leaves Sydney to return to the place she grew up, taking refuge in a small religious community hidden away on the stark plains of rural Australia. She doesn't believe in God, or know what prayer is and finds herself living this strange, reclusive existence almost by accident. But disquiet interrupts this secluded life with three visitations. First comes a terrible mouse plague, each day signaling 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.

Four older women have a lifelong friendship of the best kind: loving, practical, frank and steadfast. But when Sylvie dies, the ground shifts dangerously for the remaining three. Struggling to recall exactly why they've remained close all these years, the grieving women gather at Sylvie's old beach house to clean it out before it is sold. Can they survive together without her? Without Sylvie to maintain the group's delicate equilibrium, frustrations build and painful memories press in. Fraying tempers, an elderly dog, unwelcome guests and too much wine collide in a storm that brings long-buried hurts to the surface --- and threatens to sweep away their friendship for good.
